A piezoelectric element 10 is a laminated type piezoelectric element including a plurality of piezoelectric layers laminated on each other; and an internal electrode layer disposed between adjacent piezoelectric layers. In the piezoelectric element 10, coating layers 12, 14 are disposed on a side surface of the piezoelectric element so as to cover at least an effective portion of the internal electrode layer that is exposed at the side surface. The coating layers 12, 14 contiguously extend from the side surface of the piezoelectric element to at least one of upper and lower surfaces of the piezoelectric element. A step is formed at the at least one of upper and lower surface of the piezoelectric element by the coating layers formed at an edge region. |
