PROBLEM TO BE SOLVED: To provide a manufacturing method for an inorganic foam-molded product, whereby a fireproof, incombustible molded product of a desired shape and size which is excellent in heat-insulating properties and has a homogeneous expansion ratio and a tough foaming structure can be produced at a low cost. SOLUTION: An appropriate volume of a solution containing a high molecular weight siloxane and silanol salt is filled in each molding machine, and the molding machines are sealed, fixed and placed in multiple stages inside a heating cage to perform heating and foam-molding in a large-capacity heating furnace or a heating kiln whose temperature can be controlled by electric or gas heating. Here, each molding machine comprises a forming die of a desired shape and size and an internal pressure-applying lid, wherein the forming die is made of a metal or a nonferrous metal and can hold the solution containing a high molecular weight siloxane and silanol salt, and the internal pressure-applying lid can be freely opened or closed or can be attached to or removed from the shaping die and can seal and fix the shaping die.
