    • PROBLEM TO BE SOLVED: To provide a resonator capable of reducing the impedance, as compared with those of conventional types, and to provide a method of manufacturing the resonator, and to provide an oscillator and electronic apparatus which is equipped with such a resonator.SOLUTION: In a vibration part 11 for performing resonance vibration by longitudinal wave vibration according to the frequency of an input AC signal Sin, not less than three insulation films 112 are provided. The total of the area (area of Y-Z end face) in respective insulating films 112 within the vibrating part 11 increases, thus reducing the impedance as compared with those of conventional types. The respective insulating films 112 may vibrate along each of two mutually orthogonal directions, within the vibration surface of the vibration part; may vibrate radially toward an outer peripheral direction from the center of a concentric circle; or may vibrate along a circulating direction in a ring-like vibrating part.
    • 要解决的问题:提供一种与常规类型相比能够减小阻抗的谐振器,并且提供一种制造谐振器的方法,并提供一种配备有这种谐振器的振荡器和电子设备。解决方案 :在根据输入的AC信号Sin的频率通过纵波振动进行共振振动的振动部11中,设有不小于3个的绝缘膜112。 振动部11内的各个绝缘膜112中的面积(Y-Z端面的面积)的总和增加,因此与常规类型相比减小了阻抗。 相应的绝缘膜112可以在振动部分的振动表面内沿着两个相互正交的方向中的每一个振动; 可以从同心圆的中心径向向外周方向振动; 或者可以在环状振动部中沿循环方向振动。
