ABSTRACT OF THE DICLOSURE A continuous molding method for a rod-like product is provided which comprises the steps of: forming an uncured rod-like molding by passing reinforcing fibers impregnated with uncured thermosetting resin through a squeezing die having a predetermined shape; extruding molten thermoplastic fluororesin in a ring shape to enclose the rod-like molding; forming a sheathing layer of the thermoplastic resin by causing the thermoplastic resin to come into contact with the outer periphery of the uncured rod-like molding and by cooling and solidifying the thermoplastic resin; introducing the uncured rod-like molding having the sheathing layer into a heated tank thereby hardening the thermosetting resin; and stripping off the sheathing layer to form the rod-like product having a surface of fiber reinforced thermosetting resin.
