1 is a piezoelectric ceramic element, 3 and 3' are lead wires, 4 is solder or conductive adhesive, and 5 is a case. Lead wires 3 and 3' are bonded to the piezoelectric ceramic element 2 formed with the lead wire 3 with solder or conductive adhesive 4, and as shown in FIG. , 3' are not touched from the outside, thereby preventing the main vibrating part from being suppressed and achieving performance. Therefore, since the case 5 covers the entire portion other than the lead wires 3 and 3', the shape of the corrugator becomes large to some extent, and there are disadvantages in that the sealing performance is poor and the quality is poor in terms of reliability.

例を詳細に説明する。 In order to eliminate the drawbacks of the above-mentioned conventional examples, the present invention provides a piezoelectric ceramic wave device that prevents the main vibration of the piezoelectric ceramic element from being suppressed by providing a space around the main vibration part of the piezoelectric ceramic element and covering it. The present invention provides a method for manufacturing. Hereinafter, embodiments will be described in detail with reference to the drawings.

A piezoelectric ceramic element 7 with an electrode 6 provided thereon so that the main vibrating part is located at the center is attached to lead terminals 9, 9' fixed by a holding plate 8 with solder or conductive adhesive 10, 10'. Figure 2b from the top of element 7
As shown in FIG. 2C, an insulating sheet 11 is placed on top of the insulating sheet 11, and a powder or liquid resin 12 is placed on top of the insulating sheet 11 as shown in FIG. At this time,
In this initial thermosetting state, as shown in FIG. If the piezoelectric ceramic element 7 is pushed upward to form a space between the insulating sheet 11 and the resin 12, and the resin 12 is cured, and an adhesive is pasted around the insulating sheet 11,
The resin may be thermally cured after the corrugator is immersed in the liquid resin bath.
以上説明したように、本発明によれば、樹脂の
