Piezoelectric element and method of manufacturing the same |
摘要 |
An array of piezoelectric elements is easily manufactured by making insulating portions at side surfaces smaller. The piezoelectric element includes: a multilayered structure in which piezoelectric material layers and internal electrode layers are alternately stacked; first insulating films formed by using an AD method, for covering a first group of internal electrode layers at a first surface of the multilayered structure; second insulating films formed by using the AD method, for covering a second group of internal electrode layers at a second surface of the multilayered structure; a first external electrode connected to the second group of internal electrode layers and insulated from the first group of internal electrode layers at the first surface; and a second external electrode connected to the first group of internal electrode layers and insulated from the second group of internal electrode layers at the second surface.
