RESONATOR ELEMENT, RESONATOR, ELECTRONIC DEVICE, ELECTRONIC APPARATUS, AND MOVING OBJECT

摘要

A quartz crystal resonator element includes a first electrode pad and a second electrode pad disposed on a lower surface of a support arm, and cut sections disposed in both principal surfaces (upper and lower surfaces) of the support arm between the first and second electrode pads so as to overlap each other, and the cut sections extend so that the support arm is cut from the side surface in the +X-axis direction of the support arm to the −X-axis direction, and are provided with first surfaces roughly perpendicular to the X axis and first and second tilted surfaces extending in the +X-axis direction.

1. A quartz crystal resonator element comprising:
a base section; a pair of vibrating arms extending from an end portion of the base section in a first direction, and arranged side by side in a second direction intersecting with the first direction; and a support arm extending from the end portion of the base section in the first direction, and arranged between the pair of vibrating arms, the support arm including:
a cut section formed in a side surface on a +X-axis side of the support arm by cutting the support arm along a −X-axis direction, and including a convex tilted portion including a first tilted surface extending from an −X-axis side toward a +X-axis side and tilted from a −Z-axis side of a Z axis toward a +Z-axis side along the +X-axis direction and a second tilted surface extending from the −X-axis side toward the +X-axis side and tilted from the +Z-axis side toward the −Z-axis side,a first electrode pad and a second electrode pad having polarities opposite to each other, anda first extraction electrode and a second extraction electrode disposed on a side surface of the support arm on the +X-axis side among side surfaces intersecting with a crystal X axis of the quartz crystal, and connected respectively to the first electrode pad and the second electrode pad, and the first extraction electrode and the second extraction electrode are electrically separated from each other in the cut section.
