PROBLEM TO BE SOLVED: To provide a wood/thermoplastic resin composite foamed molded product with a hollow therein, having light weight, a cross section similar to a pattern of a natural tree, an excellent secondary workability and a recycling property, and to provide a manufacturing method for the same. SOLUTION: The extrusion-molded wood/thermoplastic resin composite foamed molded product, which contains 40 to 80 wt.% of wood, 60 to 20 wt.% of a thermoplastic resin and a foaming agent, has a hollow in the middle of the cross section crossing the extrusion-molding direction and has a density gradient to continuously increase from the peripheral edge of the hollow to the surface.
