Abstract: A sticking material for hemostasis has a flexible strip-shaped base member having a high recovery property, a main surface, and side edges extending in a first longitudinal direction. An adhesive layer is disposed on the main surface of the base member. A pad is disposed on the adhesive layer and extends in a second longitudinal direction substantially transverse to the first longitudinal direction such that a space is defined between the pad and each of the side edges of the base member. The pad is of a size sufficient to exert pressure at a puncture area including punctures of both a blood vessel and a skin surface. The pad has a slight elasticity and a hardness capable of securely exerting pressure on the punctures by a shrinking action of the base member when the base member is adhered to the skin surface while being stretched to secure the pad over the punctures.
