Abstract
A quartz crystal resonator unit includes a quartz crystal resonator that includes a quartz crystal blank. A pair of excitation electrodes are disposed on opposed main surfaces of the quartz crystal blank so as to face each other. A pair of connection electrodes are electrically connected to respective ones of the pair of excitation electrodes. A base member has a surface on which the quartz crystal resonator is mounted. A lid member is joined to the surface of the base member via a joining member. The quartz crystal resonator is accommodated in an inner space defined by the lid member and the base member on the surface of the base member. Parts of the joining member that cover protruding portions are in contact with a side wall of the lid member so as to restrain movement of the lid member when seen in a plan view in a direction normal to the surface of the base member.
