OSCILLATOR, ELECTRONIC APPARATUS, AND VEHICLE

An oscillator includes: a base substrate having a first electrode; a temperature control element mounted on the base substrate and having a first pad electrically coupled to the first electrode; a resonator element having a first major surface and a second major surface in front-back relation with the first major surface, and mounted on the temperature control element in such a way that the second major surface faces the temperature control element; and at least one first bonding wire coupling the first major surface and the first pad together.
