摘要： Provided is a highly durable laminated piezoelectric element wherein a stress generated at a portion, i.e., the boundary between an active region and inactive region, is reduced. A method for manufacturing such laminated piezoelectric element is also provided. The laminated piezoelectric element has a laminated structure (15) wherein a plurality of piezoelectric layers (11) and internal electrode layers (13) are alternately laminated. The piezoelectric layer (11) contains a metal element other than those elements constituting piezoelectric ceramic, i.e., the main component of the piezoelectric layer (11), and at a portion (11a) of the piezoelectric layer (11) at the vicinity of an end of the internal electrode layer (13), metal particles having a metal element as a main component exist. The content of the metal at the portion (11a) at the vicinity of the end is higher than the content of a compound of the metal element and a nonmetal element.
