The actuator body has a piezoelectric ceramic substrate and first and second electrodes. The piezoelectric ceramic substrate has first and second principal surfaces, first and second side surfaces, and first and second edge surfaces. The first electrode has a first external electrode portion formed on a part of the first principal surface, and a second external electrode portion formed on the first edge surface. The second electrode has a third external electrode portion formed on the second edge surface, and a fourth external electrode portion formed on the first principal surface. Each of: at least a part of each of the first and second external electrode portions; and at least a part of each of the third and fourth external electrode portions, constitutes a joined portion mounted on the substrate by an electrically-conductive agent. The coating film covers at least a part of a surface of a portion of the actuator body other than the joined portions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic head driving piezoelectric ceramic actuator","description":"A magnetic head driving piezoelectric ceramic actuator having an actuator body and a coating layer.
