A vibrator includes a vibrator element and a base on which the vibrator element is installed. In addition, when n is set to a natural number equal to or greater than 2, and j is set to a natural number equal to or greater than 1 and equal to or less than n, the vibrator element includes n inherent vibration modes having resonance frequencies different from each other, and when a resonance frequency of a main vibration of the vibrator element in the n inherent vibration modes is set to ωin a relationship between an arbitrary integer kand a resonance frequency ωcorresponding to each of the n inherent vibration modes, the following three expressions are all satisfied.
