Claim 11:
12. A vibrator device comprising:
a vibrating body including a vibrator element and a support substrate, the support substrate 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 support substrate of the vibrating body has a coupling part including a recess defined in the support substrate, the recess being recessed from the side surface of the support substrate 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,
the support substrate is disposed between the vibrator element and the package,
the support substrate of the vibrating body includes a first coupling part and a second coupling part as the coupling part,
the protrusion in the first coupling part protrudes in a first direction, and
the protrusion in the second coupling part protrudes in a direction different from the first direction.
