Abstract
A quartz crystal resonator unit including a quartz crystal resonator having a quartz crystal blank, a frame surrounding an outer periphery of the quartz crystal blank, and coupling members connecting the frame to the quartz crystal blank. Moreover, a lid member and a base member are attached to the frame and seal the resonator. One or more outer electrodes is formed over end surfaces of the frame, the lid member, and the base member on a side where the coupling members are coupled. The one or more outer electrodes has a machinery quality factor smaller than that of the frame.
