PURPOSE: To improve a fun in use of toy cracker remarkably by a method wherein an explosive part is formed of a plurality of outer and inner explosive layers, ignition temperatures of the inner explosive layers are increased in sequence more than that of the outer explosive layers and their combustion speeds are reduced.

CONSTITUTION: An explosive part 1 is formed of a plurality of inner and outer explosive layers 2, 3, 4.... That is, the explosive part 1 is formed by two explosive layers 2 and 3, for example. At these explosive layers, ignition temperatures of the inner explosive layers are higher in sequence than those of the outer explosive layers and their combustion speeds are slower in sequence. For example, as the inner explosive layers 2, iron powder comprised of barium nitrate and iron powders are applied and further as the outer explosive layers 3, a flame agent composed of potassium perchlorate and copper oxide is used. Ignition explosive 7 is filled at an extreme end of the explosive part 1. The ignition explosive 7 has as its major substance, metallic oxide and metallic powder acting as reducing agent, and binder of starch is used in the explosive 7.
