A catheter molding apparatus that includes a fore-stage extrusion molding device for extrusion molding an inner layer tube of resin so as to fit a core wire material of metal therein, a braided layer attaching unit for attaching a braided layer made by the braiding of a reinforcing thread to the outer surface of the inner layer tube molded by the fore-stage extrusion molding device and once cooled, thereby molding a braided tube. The apparatus also includes a post-stage extrusion molding device for extrusion molding a raw material tube for a catheter by fitting an outer layer tube of resin thereon, and a take-off unit for taking off the raw material tube. The fore-stage extrusion molding device, braided layer attaching unit, post-stage extrusion molding device, and take-off unit are continuously disposed along the longitudinal direction of the tubes.
