Abstract:
A quartz crystal resonator includes a quartz crystal resonator element, a thermistor, a second layer including a first principal surface and a second principal surface, and a third layer having a through hole. internal terminals are provided on the first principal surface side, and electrode pads are provided in a portion exposed from the through hole on the second principal surface side. The quartz crystal resonator element is attached to the internal terminals, and the thermistor is attached to the electrode pads. Two mounting terminals are provided on a first diagonal line on the third principal surface side of the third layer, and two mounting terminals are provided on a second diagonal line. At least one of the two electrode pads is connected to any one of the two mounting terminals on the second diagonal line through a first conductive film provided on an inner wall of the through hole.
