Abstract:
A piezoelectric device according to the present invention includes lead wires (12) each having one end electrically connected to a circuit pattern, and a piezoelectric oscillator (13) made of quartz and having terminals (13a) electrically connected to the other ends of the lead wires (12), wherein the terminals (13a) of the piezoelectric oscillator (13) and the lead wires (12) are respectively capacitively coupled with each other via an insulation layer (14). According to the structure, the piezoelectric device can reduce its vertical height.
