Resonator element and resonator device

Abstract

A resonator element includes a quartz crystal substrate having a first surface along an X-axis and a Z'-axis of a quartz crystal and having a quadrangular shape in plan view including a first outer edge intersecting the X-axis, a first excitation electrode disposed on the first surface of the quartz crystal substrate and having a quadrangular shape in plan view including a first side intersecting the X-axis, a first mount electrode disposed on a side of the first outer edge of the quartz crystal substrate and connected to the first excitation electrode, and a first lead-out electrode connecting the first excitation electrode and the first mount electrode. The resonator element has a non-electrode region, in which the quartz crystal substrate is exposed, between the first outer edge of the quartz crystal substrate and the first side of the first excitation electrode.
