COMPLEX PIEZOELECTRIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a complex piezoelectric device which improves the productivity.

SOLUTION: A complex piezoelectric device includes: a device mounting part 310 including a substrate part 310a having first and second main surfaces and a leg part 310b provided on the second main surface of the substrate part 310a; a first piezoelectric device 100 which includes a first element mounting member 110 having a first recessed space K1 and a first piezoelectric vibration element 120 mounted in the first recessed space K1 and is joined to the first main surface of the substrate part 310a; and a second piezoelectric device 200 which includes a second element mounting member 210 having a second recessed space K2 and a second piezoelectric vibration element 220 mounted in the second recessed space K2 and is joined to the second main surface of the substrate part 310a.
