ABSTRACT:
A molded article of a fiber-reinforced thermoplastic resin which suffers less deformation and has good appearance is produced by a method which includes the steps of:
supplying at least two porous fibrous sheets,
supplying a resin melt of a thermoplastic resin in a space between the porous fibrous sheets, and
forcing the resin melt to fill the pores of the porous sheets by resin supplying pressure and/or pressing pressure and to reach outer surfaces of the porous fibrous sheet.
