The material may further flow into the small recesses so that they solidify integrally.

On the other hand, a mold 3 as shown in FIG. 3 is prepared.
The mold frame 3 is open at the top, and the interval between the two long side plates 3b facing above the bottom plate 3a is the interval at which the head of the chopstick material body 1 is fitted, and one of the long side plates 3b The other side is connected by another side plate 3c, and the other side is open.
The material of the mold 3 is not limited, and may be any material such as wood, casting, plastic, or ceramic.
The frame 3 has an opening in the upper part of the long box shape and one side of the narrower side. The narrower side is the diameter of the head of the main body 1 of the chopstick material. The depth inside the mold 3 is practically equal to or larger than the diameter of the head of the main body 1.

The process for forming a decorative body according to the present invention is as follows.
First, as shown in FIG. 4, the main body 1 of the chopstick material provided with the hole 2 is placed between the top surface of the head and the side plate 3 c facing the side opening of the mold 3 with a space therebetween. It fits into the mold 3 from above, and the middle and the tip of the main body 1 are projected from the mold 3.
The mold 3 is closed on the side by the top surface of the main body 1, and a vacant chamber 4 having an open top is formed.

The next step is shown in FIG.
In this step, a resin adhesive 5 (including a paint that dries and solidifies) 5 that is dried and solidified is injected into the vacant chamber 4 up to the opening surface of the vacant chamber 4 or a slightly larger number of eyes.
The injected resin adhesive 5 also flows into the hole 2 as shown in FIG.

  When the injection step of the resin adhesive 5 is completed, the resin adhesive 5 is naturally dried or forcedly dried by blowing air or the like to be solidified.

When the resin adhesive 5 is solidified, the mold 3 is removed from the solidified body 5a and the main body 1 of the chopstick material.
The solidified body 5 a has a rod-like body 6 in the hole 2 of the main body and protrudes into the head of the main body 1.

  In the next step, the corners and surfaces of the main body 1 and the solidified body 5a are cut and polished, and a paint is applied to the surfaces. The coating method of the paint is not limited and is performed by a known method. When the tip portion of the solidified body 5a is gripped with a tool at the time of applying the paint, since the paint is not applied to the gripped portion, the portion is cut and the cut surface is polished and shaped, and then the paint is applied.

When the paint is dried, the chopsticks with the solidified body 5a fixed as a decoration on the head of the chopsticks are completed.
The finished chopstick decoration is bonded and firmly fixed on the top surface of the chopstick material body 1 and the wall surface of the hole 2.
Further, when the shape of the hole 2 is diverging toward the bottom, the rod-like body 6 solidified in the hole 2 continuously from the solidified body 5a does not come out of the hole 2, so that the decorative body is more firmly attached to the chopstick body. Secure to.

Another embodiment is a method of forming a decorative body in which beads, small dried flowers, and other small objects are included in the solidified body 5a.
