A molding material is provided including a composite having 1 to 50 wt % of (A) a bundle of continuous reinforcing fibers and 0.1 to 40 wt % of (B) a polyarylene sulfide prepolymer or (B') a polyarylene sulfide; and 10 to 98.9 wt % of (C) a thermoplastic resin adhered to the composite; wherein the composite further has (D) a zero-valent transition metal compound or (E) a low-valent iron compound in an amount of 0.001 to 20 mol % based on the amount of sulfur atoms contained in the component (B) or (B&#x2032;). A prepreg and a method of producing a fiber-reinforced molding base material is also provided. By using the molding material according to the present invention which exhibits excellent economic efficiency and productivity, a molded article having excellent mechanical characteristics can be easily produced.
