Piezoelectric element and method of manufacturing the same

摘要

A piezoelectric element (10) includes first internal electrodes (12) and second internal electrodes (13, as well as piezoelectric ceramic layers (11) that are made of ceramics and arranged between the first internal electrodes and second internal electrodes. Manganese is present relatively more abundantly in the areas (11b) of the piezoelectric ceramic layers adjacent to the first internal electrodes and second internal electrodes, compared to at the centers of the piezoelectric ceramic layers. Insulation performance of the piezoelectric element is kept from dropping over the course of use.
