A resonator device capable of preventing the characteristics of the resonator element from degrading while ensuring the fixation strength of the resonator element is provided. A vibrator as the resonator device includes a heat generation element as a base body, a first support arm and a second support arm as elastic members each constituting a plate spring having one end connected to the heat generation element and extending from the one end toward the other end disposed at a position distant from the heat generation element, and a resonator element connected to a first support section and a second support section respectively disposed on the other end side of the first support arm and the second support arm so as to be distant from the heat generation element.
