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.
