PROBLEM TO BE SOLVED: To provide a disposable body warmer which absorbs sweat even in the case of perspiration, keeps the skin contact surface not wet nor sticky, and sticks to the inner surface of underwear. SOLUTION: A flat bag 10 with a sealed-in heating composition 40 is formed as a four sides-sealed one. In a surface-constituting member 20 on the side of adhesion to the skin, a first nonwoven fabric 21 with hydrophobicity and water permeability, serving as the outer layer, and a second nonwoven fabric 22 with water absorbing properties and water retention, serving as the intermediate layer, are superposed on each other by adhesion or welding so as not to inhibit air permeability; and additionally, a sealant film 23 serving as an inner layer is superposed on the second nonwoven fabric 22. In a surface-constituting member 30 on the side of application to the inner surface of the underwear, a third nonwoven fabric 31 with air permeability, serving as an outer layer, and a sealant film 32 with air permeability, serving as the inner layer, are bonded or welded together so as not to inhibit the air permeability; a sticky coating film 33 is applied and formed on the third nonwoven fabric 31 so as not to inhibit the air permeability; and a separator 34 is superposed on the sticky coating film 33.
