PROBLEM TO BE SOLVED: To reflect a change in the shape of an actual human body precisely, and to scale a musculo-skeletal model efficiently in a technique for creating, on a computer, the musculo-skeletal model for expressing a human body on the computer. SOLUTION: The musculo-skeletal model has, for each rigid segment for expressing each bone, a joint point C for defining the position of a joint; an attachment A for defining an attaching position at which a muscle is attached to each bone; and a passing point B for defining the route where the muscle is extended from the attaching position of each bone to another bone. For creating a musculo-skeletal model for expressing a human body having a different shape by performing coordinates conversion based on an inputted scaling magnification (k) with the musculo-skeletal model created in advance based on a specific shape for the human body as a master model, coordinates conversion (scaling in a narrow sense) is performed to each coordinates value of the joint point and the attaching point, based on the inputted scaling magnification, and coordinates conversion (translation motion integral with the junction point) differing from the coordinates conversion is made to the coordinates value of the point which is passed through.
