Resonator device, electronic device, and moving object

A resonator device comprising:

• a substrate having first and second principal surfaces opposite to each other, the second principal surface having a recess therein so that the substrate has a ledge on the second principal surface, the substrate being in a substantially rectangular shape so as to have a first long side and a second long side that are parallel to each other in a plan view, and two short sides that intersect the first and second long sides in the plan view;
• a resonator element mounted on the first principal surface of the substrate;
• a thermo-sensitive element mounted in the recess of the second principal surface of the substrate via a bonding material, the thermo-sensitive element having first and second electrodes at opposite ends, respectively;
• and
• a plurality of electrode terminals respectively disposed at corners of the substantially rectangular shaped substrate so as to be located on the ledge of the second principal surface of the substrate and spaced apart from an opening of the recess in the plan view, the plurality of electrode terminals being connected to one of the resonator element and the thermo-sensitive element,
• wherein a first distance in a first direction perpendicular to the first principal surface from a mounting surface of one of the plurality of electrode terminals to an outer surface of the thermo-sensitive element is equal to or longer than 0.05 mm,
• a second distance in the first direction from the mounting surface of one of the plurality of electrode terminals to a first inner surface of the recess, on which the thermo-sensitive element is mounted, is less than 0.3 mm,
• the outer surface of the thermo-sensitive element that is free from the bonding material is exposed to an inner space of the recess, and
• the first and second electrodes are arranged along a virtual straight line in the plan view, and the virtual straight line intersects one of the short sides of the substrate in the plan view,
• the plurality of electrode terminals includes:
• a first electrode terminal and a second electrode terminal that are disposed adjacent to the first long side of the substrate;
• and
• a third electrode terminal and a fourth electrode terminal that are disposed adjacent to the second long side of the substrate in the plan view,
• the first electrode terminal has a protrusion protruding toward the second electrode terminal, and
• a third distance between the first electrode terminal and the second electrode terminal is shorter than a fourth distance between the third electrode terminal and the fourth electrode terminal.
