<P>PROBLEM TO BE SOLVED: To provide a method for producing prepreg having an improved impregnating property of a fiber substrate with a resin varnish containing an inorganic filler, to provide the prepreg using the method, and to provide a laminated sheet. Ž<P>SOLUTION: The method for producing the prepreg includes: a step of preparing for the substrate; a step (i) of impregnating the substrate with a coating liquid (A) containing a resin component (a1) and a solvent (a2) without containing an inorganic filler; and a step (ii) of further impregnating the substrate with a coating liquid (B) containing a resin component (b1), a solvent (b2), and the inorganic filler (b3) after the step (i) of impregnating.
