Laminate-type piezoelectric device and method for manufacturing the same

摘要

A laminate-type piezoelectric device includes: a piezoelectric layer ( 2 ); and an internal electrode layer ( 3 ) which is laminated on the piezoelectric layer ( 2 ), has a lower surface flat along a surface of the piezoelectric layer ( 2 ) and has an edge sidewall in its tip portion having an inclined surface ( 3 A) making an acute angle with respect to the surface of the underlying piezoelectric layer ( 2 ). The piezoelectric layers ( 2 ) and the internal electrode layers ( 3 ) are alternately laminated on each other.
