<P>PROBLEM TO BE SOLVED: To provide a method of forming a piezoelectric resonator having a resonation structure. <P>SOLUTION: According to this method, it is possible to simplify a manufacturing process of the piezoelectric resonator and raise the yield of the resonation structure from a molding in the manufacturing process. The method includes preparing a base structure, a protection structure and a molding. The molding has polarized electrodes on selected two different surfaces, respectively. The molding has crystals having polarization axes aligned parallel to each other toward a predetermined direction. Resonant plates are formed by cutting the molding and the polarized electrodes to a predetermined width. Resonant electrodes are formed on the resonant plates. Resonation structures are formed by cutting the resonant electrodes and the resonant plates. Finally, a piezoelectric resonator is formed by interposing the resonation structure between the protection structure and the base structure. <P>COPYRIGHT: (C)2008,JPO&INPIT |
