摘要：An AT-cut crystal resonator plate (2) includes a first main surface (2a) on which afirst excitation electrode (211) is formed and a second main surface (2b) on which asecond excitation electrode (212) is formed. The AT-cut crystal resonator plate (2)further includes: a substantially rectangular-shaped vibrating part (21) that is
piezoelectrically vibrated when a voltage is applied to the first excitation electrode (211)and the second excitation electrode (212); a holding part (22) protruding from a cornerpart (21a) of the vibrating part (21) in a Z' axis direction of the AT-cut crystal; and anexternal frame part (23) configured to surround an external circumference of thevibrating part (21) and to hold the holding part (22).
