Abstract
A resonator element includes a base portion and a pair of vibrating arms that are provided integrally with the base portion and extend in a Y-axis direction from a distal end of the base portion. When the lengths of the vibrating arms are set to L and the lengths of hammerheads are set to H, a relation of 0.183≦H/L≦0.597 is satisfied. When a resonance frequency of a basic vibration mode is set to ω0 and a resonance frequency of a vibration mode different from the basic vibration mode is set to ω1, a relation of (|ω0−ω1|)/ω0≧0.124 is satisfied.
