Abstract
Official abstract text for this publication.
A resonator element includes a base portion, and a vibrating arm which extends from the base portion and on which a weight portion is provided, and the weight portion includes a first weight portion which is disposed on one main surface of a distal end portion of the vibrating arm, and a second weight portion which is disposed on the distal end side with respect to the first weight portion and has a thickness smaller than that of the first weight portion. The vibrating arm transmits an energy beam, and a laser incidence area where incidence of the energy beam to the inside of the vibrating arm is allowed, is disposed in a position of the other main surface on the opposite side of the vibrating arm overlapped with the second weight portion.
First claim
