Claim 10:
11. 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 coupling part has an electrode on at least one of the principal surfaces, and is electrically coupled to an interconnection at the package side via the bonding material, and
the electrode is also disposed on the side surface of the protrusion.
