Abstract
A piezoelectric resonator includes a mother resonator element which is fixed on a bottom of a continuous storing groove which is formed in a mother base plate. An upper opening of the storing groove is covered with a mother cover plate, so that the mother base plate, the mother cover plate and the mother resonator element are simultaneously cut along a direction perpendicular to a lengthwise direction of the storing groove to form intermediate chips. Side openings of each of the intermediate chips are covered with side plates, and thereafter external electrodes are formed on outer surfaces of each of the completed chips.
