Resonator device

A resonator device comprising:

• a base having a first surface and a second surface that are in front-back relation;
• a resonator element that is located at a first surface with respect to the base and that includes a resonation substrate and an electrode disposed at a surface of the resonation substrate on a base side;
• a conductive layer that is disposed at the first surface and that includes a joint portion joined to the electrode;
• and
• a stress relaxation layer that is interposed between the base and the conductive layer and that at least partially overlaps with the joint portion in a plan view of the base,
• wherein the stress relaxation layer includes an exposed portion exposed from the conductive layer;
• the conductive layer includes the joint portion, a wiring portion disposed at the first surface, and a coupling portion that couples the joint portion and the wiring portion;
• the coupling portion includes a first coupling portion extending to a plus side in a first direction and a second coupling portion extending to a minus side in the first direction;
• and
• the coupling portion further includes a third coupling portion extending to a plus side in a second direction intersecting with the first direction, and a fourth coupling portion extending to a minus side in the second direction.
