PROBLEM TO BE SOLVED: To provide a thermoplastic resin made molded product constituted by heat-sealing libs in part of a thermoplastic resin made foamed sheet and having good appearance and a producing method of the same. SOLUTION: In the thermoplastic resin made molded product and the producing method of the same, the ribs 7 are heat-sealed to a part of the thermoplastic resin made foamed sheet 1, the shape of the ribs 7 satisfies 1 mm≤(V<SB>1</SB>/S<SB>1</SB>)≤9 mm, wherein V<SB>1</SB>is the volume (mm<SP>3</SP>) of the ribs and S<SB>1</SB>is the area (mm<SP>2</SP>) of the heat-sealed portions of the ribs. The thermoplastic resin made molded product is produced by supplying the softened thermoplastic resin made foamed sheet 1 between a shaping mold in whose shaping face recessed portions whose volume and area of opening portion satisfies 1 mm≤(V<SB>2</SB>/S<SB>2</SB>)≤9 mm, wherein V<SB>2</SB>is the volume of the recessed portion and S<SB>2</SB>is the area of the opening portion of the recessed portion, and a shaping mold which constitutes a pair along with the above shaping mold for shaping the ribs 7.
