<P>PROBLEM TO BE SOLVED: To provide a stacked piezoelectric element having an insulation structure excellent in durability by improving bonding performance of an insulating resin, and to provide a manufacturing method thereof. <P>SOLUTION: The stacked piezoelectric element 1 has a ceramic laminate 10 formed by alternately laminating a piezoelectric layer 11 made of a piezoelectric material and inner electrode layers 21, 22 having conductivity. In the element 1, an external electrode is joined to the side surface 103 of the ceramic laminate 10, and the entire side surface 103 of the ceramic laminate 10 is molded with an insulating resin 35. An anchor layer 13 having unevenness on its external surface is formed on the surface layer of the ceramic laminate 10 contacting the insulating resin 35. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
