Abstract
Provided is a piezoelectric device capable of improving measurement precision of a temperature of a piezoelectric element. A piezoelectric device (1) includes a package (2) including a housing member (4) having a thermistor substrate (3) and a frame (7) provided to project from a first main surface (3a) of the thermistor substrate (3) and in which a housing part (6) is formed by the first main surface (3a) and the frame (7) and a lid (9) provided on the frame (7) to cover a space (5) of the housing part (6), and a piezoelectric vibration element (5) provided on the first main surface (3a) of the thermistor substrate (3) in the housing part (6), wherein the thermistor substrate (3) is a multilayer negative temperature coefficient (NTC) thermistor.
