Abstract
A piezoelectric device has a plate-shaped substrate, a first frame defining a first concave portion at one surface of the substrate, a second frame defining a second concave portion at the other surface of the substrate, a first electrode member provided at one surface of the substrate, a second electrode member provided at the other surface of the substrate, a piezoelectric unit in which a first electrode section of the piezoelectric vibration plate is fixed to the first electrode member by a conductive binder, a cover sealing the first concave portion, and a temperature detection unit in which a second electrode section of the thermistor element is fixed to the second electrode member by a conductive joining material.
