RESONATOR ELEMENT, RESONATOR, ELECTRONIC DEVICE, AND ELECTRONIC APPARATUS
First Claim
1. A resonator element comprising at least one resonating arm that vibrates in a torsional mode,wherein the resonating arm includes a structural portion having a first portion disposed in a first direction in a sectional view in the width direction and a second portion connected to the first portion so that the center of gravity departs from the center of gravity of the first portion in the first direction and a second direction perpendicular to the first direction,wherein the first portion vibrates in a stretch mode in the length direction of the resonating arm with an application of a voltage, andwherein the second portion does not substantially vibrate in the stretch mode in the length direction of the resonating arm with the application of the voltage or vibrates in a stretch mode with a phase different from that of the first portion.
