PROBLEM TO BE SOLVED: To provide a resonator which conducts adjustment operations of a resonance frequency efficiently. SOLUTION: As an adjustment bolt 15 to adjust the resonance frequency is constituted of an adjustment bolt main body 16 and a fine adjustment bolt 17 which is movably provided inside the adjustment bolt main body 16 and faces its tip portion into a cavity 12 of a housing 13, the main body can be adjusted by the fine adjustment bolt hereafter even though the adjustment bolt main body rotates delicately in the case that the adjustment bolt main body is fixed to the housing. The adjustment operation of the resonance frequency is conducted efficiently thereby. COPYRIGHT: (C)2008,JPO&INPIT
