PPROBLEM TO BE SOLVED: To provide a granular porous gunpowder having a high rate of gas evolution in combustion and a method for producing the same. PSOLUTION: The method for producing the granular porous gunpowder includes a step of preparing a lacquer comprising a gunpowder component, an organic solvent and a nitrate and/or a sulfate, a step of preparing a granulation aqueous solution having specific gravity (20°C) of 1.0-1.1, and a heating step wherein the lacquer is added to the granulation aqueous solution and the granulation aqueous solution is heated under stirring to a temperature exceeding a boiling point of the organic solvent. The porous gunpowder has tentative specific gravity of 0.5-0.9 g/cmSP3/SP. PCOPYRIGHT: (C)2009,JPO&INPIT
