    • An AT-cut crystal resonator plate (2) includes a first main surface (2a) on which a first excitation electrode (211) is formed and a second main surface (2b) on which a second 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 corner part (21a) of the vibrating part (21) in a Z' axis direction of the AT-cut crystal; and an external frame part (23) configured to surround an external circumference of the vibrating part (21) and to hold the holding part (22).
    • AT切割水晶振动片(2)具备形成有第一激励电极(211)的第一主面(2a)和形成有第二激励电极(212)的第二主面(2b)。 AT切割水晶振动片(2)还具备:大致矩形状的振动部(21),其在对第1激励电极(211)和第2激励电极(212)施加电压时被压电振动; 保持部(22),其从振动部(21)的角部(21a)向AT切割结晶的Z'轴方向突出; 以及外框部(23),其以包围所述振动部(21)的外周的方式保持所述保持部(22)。
