To provide a method for manufacture of an operatable actuator by saving many processes by employing only stereo lithography as the process for manufacture and burying parts such as a bearing, a coil, a magnet, a sensor and the like after lamination for performing integral manufacture.

In the stereo lithography, a solid body is manufactured by curing a photo-setting resin 2 by an ultraviolet laser 3 to be laminating the same. In this case, parts such as a bearing 5, a coil 10, a magnet 8, a sensor 11 or the like constituting an actuator are inserted into the resin during the process of laminating fixed parts or movable parts movable relatively to the fixed parts or after the lamination, and a resin molded product wherein the movable parts is allowed to be moved, is integrally manufactured.
