The main body includes an inner tubular heat shrinkable sheet, a bag, and an outer tubular heat shrinkable sheet. The bag is arranged to surround the inner tubular heat shrinkable sheet and includes an exothermic reactant. A liquid storing member is arranged to surround the bag and includes a plurality of through cells. The outer tubular heat shrinkable sheet surrounds the liquid storing member and is sealed with both tip end parts of the inner tubular heat shrinkable sheet. |
