1. A sensor actuator, comprising:
a movable body on which an image sensor having an imaging plane is disposed;
a fixed body, configured to accommodate the movable body; and
a driver, configured to provide a driving force to move the image sensor,
wherein the driver comprises a plurality of wires which have lengths that vary to provide the driving force when power is applied to each of the plurality of wires,
wherein each of the plurality of wires is configured to have a first end coupled to the fixed body and a second end coupled to the movable body,
wherein one of the first end and the second end of each of the plurality of wires is connected to the fixed body or the movable body through an elastic portion,
wherein the plurality of wires comprise a first wire portion, a second wire portion, a third wire portion, and a fourth wire portion,
wherein each of the first wire portion to the fourth wire portion comprise two wires, and
wherein each of the first wire portion to the fourth wire portion is configured to have the first end fixed to the fixed body and the second end fixed to the movable body.
