PIEZOELECTRIC DEVICE, ELECTRONIC DEVICE USING THE SAME, AND AUTOMOBILE

摘要

Disclosed is a piezoelectric device comprising a lead wire (12) having an end electrically connected to a circuit pattern, and a crystal piezoelectric transducer (13) having a terminal (13a) electrically connected to the other end of the lead wire (12). Namely, this piezoelectric device has such a structure wherein the terminal (13a) of the piezoelectric transducer (13) and the lead wire (12) are capacitively coupled through an insulating layer (14). Consequently, this piezoelectric device can be reduced in height.
