Abstract
A stacked piezoelectric resonator and a characteristics-adjusting method therefor from which a desired capacitance can be obtained without changing outer dimensions of stacked piezoelectric resonators and without changing the design of a mother substrate used for forming a base for the resonators. A stacked piezoelectric resonator includes the base on which piezoelectric layers and internal electrodes are mounted. Each of the stacked surfaces of the piezoelectric layers and internal electrodes is arranged at an angle so as not to be perpendicular relative to a length of the base. The internal electrodes are alternately covered by insulators, and the external electrodes are disposed thereon and alternately connected to the internal electrodes arranged adjacent to each other to the external electrodes. To obtain the base, the mother substrate on which the piezoelectric layers and the internal electrodes are mounted is cut at an angle so as not to be perpendicular relative to each of the stacked surfaces.
