  • Publication number: 20210237202
    Abstract: A method of manufacturing a vibrator device includes preparing a vibrator element including a vibrating arm and a weight provided to the vibrating arm, and irradiating the weight with a laser beam to remove apart of the weight. Further, in the step of irradiating the weight with the laser beam to remove the part of the weight, the part of the weight is irradiated with the laser beam to thereby provide the weight with a removed area where the part of the weight is removed, and an unremoved area where the weight is not removed, and in an area close to the unremoved area in the removed area, an amount of irradiation with the laser beam is gradually increased in a direction from the unremoved area side toward the removed area.
