Abstract:
A laminated piezoelectric element, comprising:a plurality of sheet members that include at least a plurality of piezoelectric sheets and that form a laminate by stacking the plurality of the sheet members; electrode patterns that include at least first electrode patterns including a plurality of individual electrodes on each one of the first electrode patterns formed between the sheet members; and through holes that pierce through at least one of the sheet members to be internal layers of the laminate at least corresponding to the individual electrodes, the through holes electrically connect at least between the first electrode patterns by each of the individual electrodes adjacent in a lamination direction of the sheet members with an electrically conductive material applied to the through holes, wherein the through holes are provided so as to prevent the through holes adjacent in a direction parallel to an alignment of the individual electrodes in the first electrode pattern from aligning along the direction parallel to the alignment of the individual electrodes in the at least one of the sheet members.
