PROBLEM TO BE SOLVED: To provide an ignition substance which has resistance force to breakage, has a size approximately equal to that of gas generating particles, and has elasticity to have the surface area approximately equal to the surface area of a powdery ignition material. SOLUTION: A foamable ignition composition effective in forming the foaming ignition substance at least partly contains a fluoropolymer bonded oxidizing agent, a plasticizer effective in softening the fluoropolymer bonded oxidizing agent, a metal fuel reacting with the fluoropolymer bonded oxidizing agent, a foaming agent effective in making the foamable ignition composition porous and a crosslinking agent effective for structurally stabilizing the foaming ignition substance and is so constituted as to form the foaming ignition substance when heated up to a prescribed temperature.
