摘要：
A heating element has an exothermic composition that generates heat by contact with air. The exothermic composition is sealed in an air-permeable bag that has an outer face made of a fibrous sheet. The air-permeable bag is formed of a laminate obtained by layering a resin film on the fibrous sheet. The laminate is formed by discontinuously bonding the fibrous sheet and the resin film. The filing rate of the exothermic composition ranges from 4 to 95%.
