Abstract: An actuator device and a method for manufacturing the actuator device, which is formed by stacking and rolling films of electrostrictive material into a cylindrical body and can ensure electrical connection with inner electrodes at both end portions of the cylindrical body. The actuator device is formed by stacking and rolling two films of electrostrictive material into a cylindrical body, the two films each having an inner electrode on one or both surfaces thereof. The cylindrical body has at least one cut portion at each end portion thereof, the cut portion being configured to reach the inner electrode (electrode pattern). By applying conductive ink to each of the cut portions, the conductive ink flows through the cut portions and reaches the inner electrodes on the films. By heat-hardening the conductive ink, it is possible to ensure electrical connection between outer and inner electrodes.

The piezoelectric ceramic plate has a pair of main surfaces, a pair of opposing first side surfaces, and a pair of opposing second side surfaces. The pair of first side surfaces are baked surfaces, and the distance between the pair of first side surfaces measured at the center in the longitudinal direction is denoted by Lc and the distance between the pair of first side surfaces measured at ends in the longitudinal direction is denoted by Le. The ratio of the difference ΔL between Le and Lc to Lc (ΔL/Lc) is 1.0% or less. The piezoelectric ceramic plate is suitably used as a piezoelectric ceramic plate having an area of each of the main surfaces of 360 mm2 or more and a thickness of 150 μm or less.
