ABSTRACT:
A compact and thin piezo-electric resonator is provided having a high air-tightness and available at a low cost, in which a piezo-electric resonator element is provided in a housing having a structure which permits adjustment of the frequency after sealing the housing. Further, a surface-mounting type piezo-electric resonator is provided, in which a piezo-electric resonator element is provided in a housing, having a structure which permits frequency adjustment through an opening provided in a base or a lid forming the housing.
