PROBLEM TO BE SOLVED: To solve the following problems: the relaxation of a muscle cannot be obtained because muscular defense acts to apply force when a body receives strong pressure when receiving a massage and the massage cannot act on the muscle or a fascia to be imparted with an effect because only rubbing a skin surface if weakening pressure.SOLUTION: By increasing a friction coefficient of a skin surface, a muscle/fascia massager can massage a muscle or a fascia with pressure not generating muscular defense. When massaging an outer muscle by two points and further massaging an inner muscle, a curved face gradually increases a contact face according to pressure to a skin to allow sharp pain threshold value increase by a tactile sense.
