PROBLEM TO BE SOLVED: To provide a cracker capable of creating a spectacular stage by blasting out emitted materials in a state of being diffused to a wide angle in the air. SOLUTION: An emitted material receiving bag 4 filled with the emitted materials 3 and opened at its front part is received and disposed at a front part of a detonating powder body 2 inside of a cylindrical body 1, and a bag opening edge 4a is integrally joined to a blast-out port edge 6a of the cylindrical body 1 to seal a blast-out port 6. The emitted material receiving bag 4 receives the blast in detonating the detonating powder body 2 and instantaneously rushes in the direction of the blast-out port 6, the emitted materials 3 are pressed by the instantaneous rushing of the emitted material receiving bag 4, a cover member 8 is pressed and opened by the emitted materials 3, and the emitted materials 3 are discharged and blasted out in the air from the blast-out port 6 in a state that the emitted materials 3 are blasted out in the distance in a state of being diffused to a wide angle in accompany with projection of the emitted object receiving bag 4 outward from the blast-out port 6 in a reserved swollen state.
