Abstract

A manufacturing method can be carried out using simple equipment and makes it possible to efficiently manufacture many continuous fiber-reinforced thermoplastic resin sheets in a short period of time. The above problem is overcome by a method for manufacturing a continuous fiber-reinforced thermoplastic resin sheet including: an impregnation step for impregnating continuous fiber with a thermoplastic resin solution containing a halogen-containing organic solvent and a thermoplastic resin containing at least one resin from among polycarbonate resins and polyarylate resins; and a solvent removal step for removing, under exposure to IR radiation, the halogen-containing organic solvent from the continuous fiber impregnated with the thermoplastic resin solution. In the solvent removal step, the distance between a heater for emitting the IR radiation and the continuous fiber is 400 mm or less, and the temperature of a heating element for radiating the IR radiation in the heater is 260° C. or higher.
