  • Patent number: 10326427
    Abstract: A resonator includes: a resonator element that includes a base portion and a resonating arm; and a base. When n is one natural number of 2 or greater and j is 1 or greater and a natural number which is less than or equal to n, the resonator element performs resonations with n inherent resonation modes. In a relationship between arbitrary integers kj and resonance frequencies fj corresponding to the n inherent resonation modes, respectively, when f1 represents the resonance frequency of the main resonation of the resonator element and a normalized frequency difference ?f is defined by ? ? ? f ? ( ? j = 2 n ? ? k j ? f j - k 1 - f 1 ) / f 1 , a relationship of |?f|?0.03 is satisfied. The arbitrary integers kj satisfy relationships of 3??j=1n|kj|?10 and n??j=1n|kj|. A ratio of an amount of a change in the resonance frequency of the main resonation, to excitation power that electrically excites the main resonation, is 20 [ppm/?W] or higher.
