PROBLEM TO BE SOLVED: To prevent steaming of skin, rash and rubor even when sticking a body warmer directly to the skin and to keep high adhering characteristic. SOLUTION: An adhesive member for a body warmer has an adhesive agent layer on one face of a base material. The water vapor transmission rate of the adhesive agent layer(temperature of 40°C, humidity of 30 %RH and the thickness of the adhesive agent layer of 100μm) is≥800g/m<SP>2</SP>day. Otherwise, the adhesive agent layer is formed on a single surface of the base material, and consists of an adhesive agent based on a polyether-based polymer having at least one alkenyl group in the molecule. It is desirable that the base material consists of two or more layers and is a laminated base material having a nonwoven fabric base material on at least one surface and that the adhesive agent layer is formed on the nonwoven fabric base material on one surface of the laminated base material. Furthermore, it is desirable that the nonwoven fabric base material is formed of fiber substances mainly consisting of sodium polyacrylate. COPYRIGHT: (C)2004,JPO
