<p>PROBLEM TO BE SOLVED: To further promote a high-output in a plate-shaped actuator of a type of pasting a linear or band-shaped elongation/contraction element which is composed of a shape memory alloy and can selectively elongate and contract on a plate-shaped elastic body, and moving a position of the length-changed elongation/contraction element.SOLUTION: A plate-shaped actuator includes: an elastic plate-shaped member which is elastically deformable; a contractible linear elongation/contraction element which is at least one linear deformable element arranged on a plane of the elastic plate-shaped member, and formed by laminating a shape memory alloy wire rod and an electric resistance wire rod in prescribed alignment; an elastic element which surrounds at least a part of the elongation/contraction element, and is elastically deformable together with the elongation/contraction element; and a linear deformable element including energization means which selectively carries electricity to the electric resistance wire rod. The elastic plate-shaped member is deformed together with a change of a length of the linear deformable element, and a deformation region of the elastic plate-shaped member is changed together with a change of a position of the length-changed liner deformable element.</p> |
