PROBLEM TO BE SOLVED: To provide an efficient production method that can reduce the number of process steps and shorten production time during robot hand element production. SOLUTION: A preimpregnation sheet 33 is laminated to a specified surface of a core material 20, then a laminated material 40 is heated. After heating, it forms a robot hand element of hollow structure by extracting the core material 20. Also, it forms a robot hand element solid core structure by heaving the core material inside. The core material can function as an abutting board for lamination of a preimpregnation sheet and as an inner mold for forming so that the preimpregnation sheet lamination process and the forming process of the robot hand element can be carried out simultaneously.
