1. A production process of a composite molded product comprising the steps of:providing a first molding die having at least one opening forming member projecting from a first forming surface and having a predetermined dimension in a lengthwise direction; providing a second molding die having at least one rib forming groove on a second forming surface at a position corresponding to a position of said at least one opening forming member; arranging a porous skin material between said first and second molding dies; supplying a base material of a thermoplastic resin at least before curing, into a cavity defined between said first and second molding dies on said first molding die side of said skin material to form a main body; and clamping said first and second molding dies and thereby applying a pressure for performing pressure molding, said at least one opening forming member contacting said second forming surface at the position of said at least one rib forming groove, with said skin material therebetween, allowing a part of said base material to flow into said at least one rib forming groove through said porous skin material to form at least a rib over said porous skin material on said second molding die side of said skin material.
