PROBLEM TO BE SOLVED: To provide a composite laminated board at a low cost by decreasing its production processes. SOLUTION: This method for producing the composite laminated board comprises the steps of applying or impregnating an epoxy resin composition (a) to a glass woven fabric, overlapping a glass nonwoven fabric on the surface applied or impregnated with the epoxy resin composition (a) of the glass woven fabric, further applying a middle layer epoxy resin composition (b) over the glass nonwoven fabric, drying by heating to produce the prepreg, then overlapping two pieces of the prepregs by putting the glass nonwoven fabric at their inside and heating with compression for forming. In the method, it is preferable to blend 80-150 pts.wt. amount of a filler in the middle layer epoxy resin composition (b) based on 100 pts.wt. total amount of the epoxy resin in the middle layer epoxy resin composition (b) and a curing agent.
