PROBLEM TO BE SOLVED: To provide a smoke easily performing the original role such as confirmation of an objective point, free from concerns of causing fire at the objective point and the surroundings, and allowing safe treatment in case of misfire. SOLUTION: A rocket 1 for scattering powder in a smoke-like manner at the time of impact is equipped with a container 6 filled with the powder 5 and having the internal pressure increased to burst by impact force of the impact. The container 6 is stored in a warhead 2. The warhead 2 is formed with a circular groove 2a, as a fragile part broken by the impact force of the impact to expose the container 6, over the whole circumference of the warhead 2 to surround the container 6.
