Abstract

A resonator element includes a quartz crystal resonator blank provided with a base portion, vibrating arms extending from one end side of the base portion, a connecting portion which is disposed on the other end side of the base portion, and a coupling portion, located between the base portion and the connecting portion, which couples the base portion to the connecting portion. When a thickness of the quartz crystal resonator blank is set to T, a width of the base portion is set to W1, and a width of the coupling portion is set to W2, a relation of 110 μm≦T≦210 μm is satisfied, and a relation of 0.469≦W2/W1≦0.871 is satisfied.
