Abstract
In a crystal resonator plate (), a support part () extends from only one corner part positioned in the +X direction and in the −Z' direction of a vibrating part () to an external frame part () in the −Z′ direction. The vibrating part () and at least part of the support part () form an etching region (Eg) having a thickness thinner than a thickness of the external frame part (). A stepped part is formed at a boundary of the etching region (Eg), and a first lead-out wiring () is formed over the support part () to the external frame part () so as to overlap with the stepped part. At least part of the stepped part that is superimposed on the first lead-out wiring () is formed so as not to be parallel to the X axis in plan view.
