Abstract
A method of manufacturing a lamination-type piezoelectric element includes forming a ceramic laminated body in which ceramic layers and inner electrode layers are alternately laminated on each other. A pair of outer electrodes are respectively joined to a pair of joining faces formed on an outer circumferential face of the ceramic laminated body. A belt-shaped outer circumferential groove portion coming into contact with an outer circumferential end portion of at least some part of the inner electrode layers is formed on the outer circumferential face of the ceramic laminated body. This outer circumferential groove portion has at least one dent portion protruding from the adjoining portion. The outer circumferential groove portion has at least one of an insulating portion made of insulating material and a conductive portion made of conductive material.
