However, such adhesives use epoxy or acrylic adhesives, and the adhesives are heated or use catalysts to cure, and room temperature curing types require heating for several hours. Even the hardening type requires several 10 minutes,
In addition, it requires heating equipment, does not solve the problem of piezoelectric element deterioration due to heating, and creates new problems of poor conductivity due to adhesive flow and lead wire movement until curing. Was.

秒に短縮することができる。 The cyanoacrylate-based conductive instant adhesive uses ethyl cyanoacrylate as a binder, mixed with silver powder, and has a curing time of 2 to 5 minutes at room temperature.
If a part of the adhesive is exposed, such as the connection between a surface and a wire, as in the connection part b, add a tertiary amine curing accelerator dropwise to increase the curing time from 5 to 10 minutes.
It can be shortened to seconds.
又、体積低効率は10-4Ω−cmオーダーであり、
電気性能は充分に半田に代替し得る。 In addition, the volumetric efficiency is on the order of 10 -4 Ω-cm,
