PROBLEM TO BE SOLVED: To provide a massage machine for accurately judging a stiffness degree to perform treatment operation. SOLUTION: The massage machine is equipped with an operation element for pressing a human body to perform treatment operation and a stiffness detection means for bringing a contact element 1 into contact with the human body under pressure. The stiffness detection means comprises a drive means 3 for pushing the contact element 1 under pressure, a push-in distance detection means for detecting the push-in distance of the contact element 1, a pressing force detection means 2 for measuring the pressing force applied to the contact element 1 and an arithmetic means for calculating the stiffness state of the human body from the change quantity of pressing force to the change quantity of the push-in distance. The stiffness state of the human body is judged from the change quantity of the pressing force with respect to the charge quantity of the push-in distance without using pressing force at a certain push-in distance place.
