Abstract: PURPOSE:To prevent ignition of heat generating agent due to moisture or water absorption inside a heat generating agent housing part by arranging a layer of hydrate inflating agent on the heat generating room opening side of a heat generating agent layer. CONSTITUTION:In the innermost part of a heat generating agent housing, a layer of self-burning heat generating agent 1 is housed. On the opening side surface of the heat generating agent 1 layer, a hydrate inflating layer 5 is arranged, and on the further opening side, a heat insulative layer 2 is arranged. On the end surface of the heat insulative layer 2, a lid 4 is provided. The lid 4 has a hole to let a certain length of fuse 3 to pass through so that it can form an ignition head 3a of a size suitable for ignition. The fuse 3 extends just before the end surface of the hydrate inflating layer 5, and a space 10 is also provided for letting pass ignition spark produced from the tip end of the fuse. Thus a fire passage for ignition spark is formed. If water enters through a gap around the ignition head 3a of the fuse 3 or from an upper lid 8 side, or through pin holes in the wall of a heating room, or if moisture in the atmosphere is absorbed, the heat insulative layer 2 absorbs moisture or water. At this time, the hydrate inflating layer 5 inflates to close the space 10 which is to work as a fire passage, interrupt the contact between the spark from a fire source arriving at the tip end of the fuse 3 and the heat generating agent 1, whereby the ignition of the heat generating agent 1 can safely be prevented.
