Abstract: In order to regularly properly define cavities for vibrating spaces in a chip-type piezoelectric-resonator which is protected with resin to be capable of surface mounting, a mother substrate comprising a piezoelectric substrate, a plurality of piezoelectric resonance elements formed thereon is prepared and bank-shaped adhesive layers are formed on respective major surfaces of the mother substrate to enclose the vibrating region, and mother sheets provided with plural cover sheets are arranged to cover both major surfaces of the mother substrate, thereby defining cavities for vibrating spaces. Then, protective resin members are applied to cover both major surfaces of the mother substrate, which in turn is divided to obtain a plurality of chip-type piezoelectric-resonators.
