Abstract
A resonator includes a base; and at least three vibrating arms having first ends connected to a front end of the base and second ends that are open ends spaced away from the front end. Each vibrating arm includes an arm portion having a part that extends from the fixed end in a direction toward the open end with a constant width and a mass-adding portion that is connected to a tip of the arm portion and has a larger width than the arm portion. An interval between the mass-adding portions is larger than an interval between the arm portions for any two vibrating arms that are adjacent to each other.
