Oscillator

Abstract

An oscillator includes: a resonator element; a circuit element electrically coupled to the resonator element and configured to output a clock signal; and a container accommodating the resonator element and the circuit element and including a substrate having a first surface on which the circuit element is mounted. The substrate includes a first electrode provided on the first surface and electrically coupled to the resonator element, a second electrode electrically coupled to the resonator element, and an output electrode configured to output the clock signal. The first electrode and the second electrode are disposed side by side in a first direction. The output electrode is disposed adjacent to the first electrode in a second direction orthogonal to the first direction. When a virtual line that passes through an end portion of the output electrode on the first electrode side and extends along the first direction is defined as a virtual line A, an interval between an end portion of the first electrode on the output electrode side and the virtual line A is larger than an interval between an end portion of the second electrode on the output electrode side and the virtual line A in the second direction.
