Abstract
A piezoelectric resonator element includes: a resonating arm extending in a first direction and cantilever-supported; a base portion cantilever-supporting the resonating arm; and an excitation electrode allowing the resonating arm to perform flexural vibration in a second direction that is orthogonal to the first direction. In the piezoelectric resonator element, the resonating arm includes an adjusting part adjusting rigidity with respect to a bend in a third direction that is orthogonal to the first and second directions.
