Provided is a heat generating bag for footwear having a comfortable temperature regardless of the state of use, namely, when staying still, walking etc., which is thin and avoids an uncomfortable feeling of the wearer. The heat generating bag for footwear is made by having a heat generating composition powder and hot-melt adhesive powder held in the pores of multiporous vegetable fiber non-woven fabrics, such fabrics being heat compressed on a mold compressor, and the obtained sheet shaped heat generating body being packed in an air-permeable bag. The heat composition is held in the pores of multiporous vegetable fiber non-woven fabric layers which are superposed by the adhesion of water. Such non-woven fabric are compressed on a mold compressor, and the obtained sheet shaped heat generating body is impregnated with water or an inorganic electrolyte and then packed in an air-permeable bag.
