<P>PROBLEM TO BE SOLVED: To provide a stacked electronic component capable of controlling short-circuiting of internal electrodes even if operated on high voltages, its manufacturing method, and a spray device. <P>SOLUTION: There is provided a stacked piezoelectric actuator 43 wherein it includes a columnar laminate 1a composed of stacked multiple piezoelectric materials 1 and multiple internal electrodes 2, and an electric field is applied to the piezoelectric material 1 with the internal electrodes 2 that pinch the piezoelectric material 1. In the laminated piezoelectric actuator 43, ends of the internal electrodes 2 of two kinds to which different polarity voltages are applied are exposed to the side surfaces 1a2, 1a2 of the columnar laminate 1a, and the residual ion concentration existing on the side surface 1a2 of the columnar laminate 1a, where the two kinds of the internal electrodes 2 are exposed, is no more than 10 μg per square centimeter. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
