Abstract:
A quartz crystal resonator unit that includes a quartz crystal resonator, a lid member and a base member defining an internal space that accommodates the quartz crystal resonator, and a sealing frame and a joining material joining the lid member and the base member to each other. In a plan view of a principal surface of the base member, the sealing frame and the joining material have a frame shape surrounding the quartz crystal resonator, and the frame shape has a uniform width.
