Abstract
A piezoelectric vibration device includes an element mounting member provided with a recessed part, a vibration element held in the recessed part, and a lid closing the recessed part. The element mounting member includes an insulating base body including an inner bottom surface of the recessed part and an inner circumferential surface of the recessed part surrounding the inner bottom surface, a pair of signal terminals which are located on an outer surface of the base body and are electrically connected to the vibration element, a GND terminal which is located on the outer surface of the base body, and a shield film which is superposed on the inner circumferential surface of the recessed part and is electrically connected to the GND terminal.
