Abstract
An object of the present invention is to provide a thin and light-weight actuator module structure comprising a multi-layer structure such as a bimorph or unimorph structure that can be formed in an arbitrary shape and deformed in an arbitrary direction, which is high in safety and durability and can be easily fabricated, as well as a method of manufacturing the same. An actuator has a structure such that a striped internal stress distribution is induced within a plane of a bending type actuator of a laminate structure, thereby allowing the actuator to bend so as to constitute a part of a cylindrical shape whose central axis is parallel to the striped direction.
