PROBLEM TO BE SOLVED: To surely generate smoke whichever part of a ball is hit by providing an outer shell in the form of a ball, a firing agent firing by an impact added to the outer shell, a smoke agent generating smoke by firing of the firing agent and a jet smoke opening part provided at an outer shell. SOLUTION: At the time of assembling, a smoke generating ball 1 to be used in the ceremony, etc., of a mallet ball, etc., a firing agent bag 3a filled with the firing agent 3 is buried in the smoke generating agent 4, which is housed in the spherical recessed part 2d of the hemi-spherical body 2a of the outer shell 2 and adhered with adhesive. Then, the hemi-spherical bodies 2a, 2b are joined by the joining surface 2c of each and fixed with adhesive. At the time of the ball 1, it is placed on a ground and the optional side of the ball 1 is hit to give an impact to the agent 3. Then, the agent 3 is fired and the agent 4 generate smoke with this firing to make the inner space of the shell 2 full of smoke. A clogging film 7 is broken by the pressure of this smoke to jet smoke from the jet smoke opening part 5.
