1. A vibrator device comprising:
a vibrating body having obverse and reverse principal surfaces and a side surface connecting the obverse and reverse principal surfaces to each other;
a package configured to house the vibrating body; and
a bonding material configured to fix the vibrating body to the package, wherein
the vibrating body has a coupling part including a recess recessed from the side surface toward a center of the principal surfaces, and a protrusion protruding from a side surface of the recess,
the protrusion is one of breaking-off parts with which a plurality of the vibrating bodies is broken off from a wafer to which the plurality of the vibrating bodies is coupled,
the bonding material has contact with a side surface of the protrusion in the recess, and
the protrusion includes a base extending from the side surface of the recess and having a constant width, and a tip which tapers inward from the base so as to become thinner as a distance from the side surface of the recess increases toward a tip end surface of the protrusion, the tip of the protrusion being thinner than the base.
