Abstract
A crystal resonator plate according to an embodiment may include: an external frame part; a vibrating part formed thinner than the external frame part; a penetrating part formed between the external frame part and the vibrating part; and a support part formed thinner than the external frame part, which couples the external frame part to the vibrating part. A connection part connecting the external frame part to the support part on one main surface includes: a flat region formed on the same plane as the support part; and an inclined region inclined with respect to the flat region. In an end part of the support part on the connection part side, at least regions and positioned on the penetrating part side are formed continuously to the flat region.
