Abstract

A vibrator element includes a vibrating section having a rectangular shape in a plan view and including a first principal surface, a second principal surface, and an excitation portion sandwiched by a first excitation electrode and a second excitation electrode and making a thickness-shear vibration, a coupling arm extending from a corner part of the vibrating section in a first direction, and a supporting arm having a side surface at one end part side coupled to the coupling arm and extending in a second direction crossing the first direction, wherein the supporting arm includes a first supporting electrode electrically coupled to the first excitation electrode and bonded to a container via an adhesive member, and a width of the coupling arm along the second direction is four or more times a thickness of the excitation portion along a third direction crossing the first direction and the second direction and equal to or smaller than a length from an end part of the supporting arm at the coupling arm side to the first supporting electrode along the second direction.
