To provide a bandage for treating the inflammation of medial epicondyle of humerus which applies an appropriate pressing force on the extensor group of the forearm without causing the blood circulation interruption.

A bandage which treats the inflammation of medial epicondyle of humerus by applying pressure on the extensor group of the forearm of a human is composed of a semi-ring, elastic, plastic clamp body 2 having a cushion 3 in the inside, and a holding tape 1 which connects both free ends of the clamp body 2 and is steplessly adjustable. The bent part 6 of the clamp body 2 is so constituted as not to contact with the forearm in wearing the bandage appropriately, and one of two parts of the clamp body worked as presser plates (2a), 2b is so constituted as to change the tensile direction of the tendon in wearing the bandage appropriately and expanded so as to apply pressure on the extensor group right before the seating on the granule.
