Abstract
Provided is a film actuator. The film actuator includes a substrate, transformation wires disposed on the substrate to be spaced apart in a first direction parallel to the substrate, fixed wires disposed to be spaced apart from the transformation wires in the first direction and disposed on both sides of the transformation wires, respectively, and fixing blocks disposed on the transformation wires and the fixed wires to be spaced apart in a second direction parallel to the substrate and intersecting the first direction. The transformation wires include a shape memory alloy.
