The heat source 1 comprises a bag 10 and a heat-generating composition 20 containing aluminum powder, calcium hydroxide powder and calcium oxide powder, enclosed in the bag 10. The bag 10 is formed by a packing material made of a base material of nonwoven fabric of which one surface is laminated with a watertight layer. The packing material is punched with a plurality of pinholes and has a water permeable rate of 13 to 81 milliliter/min/1cm 2 measured when head of water is 27cm. The heat source 1 can satisfy preferable heating conditions including rate of temperature rise of the food, risen temperature of the food, duration of the risen temperature of the food under conditions in which a food heating device is conventionally used. Accordingly, a food heating device using the heat source capable of causing a rapid and stable heat-generating reaction can be provided.
