<P>PROBLEM TO BE SOLVED: To provide a motion intensity estimation system, capable of improving estimation precision to motion intensity at each sensor-mounted body part, while providing position-free estimation of motion intensity for a portable machine-mounted body part of a motion executer. Ž<P>SOLUTION: The motion intensity estimation system is provided with a motion sensor to detect motion generated at the body of the motion executer to estimate motion intensity of the motion executer based on result of detection by the motion sensor. Relation between a plurality of characteristic quantities as parameters to indicate motion intensity, learned for each body part on which the motion sensor is mountable, and class of motion intensity is stored in a learned value memory means. Each characteristic quantity is extracted based on the result of detection by the motion sensor, and the body part where the motion sensor is mounted is identified. Based on the extracted characteristic quantity and the identified body part where the motion sensor is mounted, motion intensity is estimated in accordance with the relation stored in the learned value memory means.
