As shown in FIGS. 1 and 2, the plate-shaped material 2 has a large number of bent hollow cylindrical members 1 arranged in the X direction (paper depth direction in FIG. 1) and the Y direction (vertical direction in FIG. 1). It is formed by arranging them in parallel in the same direction (so that the bending directions face the same direction) and adhering the tubular members 1 to each other. As a result, the inner peripheral surface of the tubular member 1 is formed as a ventilation hole 1a. In this embodiment, the tubular member 1 has a square cross section. The tubular member 1 is formed by cooling a thermoplastic material in which a fiber material having a component that does not transmit ultraviolet rays is kneaded into a cylindrical shape. The fiber material may be a plant fiber such as cotton or linen, an animal fiber such as silk or wool, or an artificial fiber such as nylon or polyester. In the present embodiment, the tubular member 1 is made by separately manufacturing half-cylindrical members cut in a plane passing through the central axis (a plane orthogonal to the X direction in FIG. 1), and bonding the semi-cylindrical members to each other. It is formed by. This makes it possible to form a plurality of bent portions in the cylindrical member 1.

The plate-shaped material 2 in the present embodiment is formed by adhering the tubular members 1 in an arranged state as described above, but the plate-shaped members can also be formed by another method.
