PROBLEM TO BE SOLVED: To provide a supporting structure of toy firework in which the firework body is supported stably on the ground surface without being tilted by air and fire balls are jetted straightly upward at all times thus ensuring a display of fireworks in safety. SOLUTION: Hooked cuts 5 are made across the opposite side wall faces 3 at the corner parts in the bottom face 4 of a tubular polygonal paper supporting box 1. Feet 6 are formed at the corner parts by extending the opposite side wall faces downward from the cuts so that the bottom face of the supporting box is supported by the feet while spaced apart from the ground surface.
