To provide an ablator, a prepreg, a method for producing an ablator, and a method for producing a prepreg for an ablator that have high reliability and can contribute to weight saving.SOLUTION: An ablator contains a fiber material and a polyimide resin and has a density of 0.6-1.3 g/cm. In a method for producing a prepreg for an ablator, a sheet-like fiber material is impregnated with a varnish containing a resin composition for forming a polyimide resin and a solvent, and the sheet-like fiber material is dried to remove the solvent.SELECTED DRAWING: Figure 1
