Abstract
A piezoelectric element includes a support member and a vibrating portion. The vibrating portion has a support region supported by the support member, and a plurality of vibration regions, one end portion side of which is supported by the support region, and the other end portion side of which is opposite to the one end portion is floating from the support member. A first vibration region in which a mass on the one end portion side is heavier than the mass on the other end portion side serves as a pressure detection section outputting a first detection signal based on the charge of the piezoelectric film. A second vibration region in which a mass on the other end portion side is heavier than the mass on one end portion side serves as an acceleration detection section outputting a second detection signal based on the charge of the piezoelectric film.
