PURPOSE: Provided is a laminated object and manufacturing method thereof, to provide a light, cost-effective yet highly strong and acoustic absorbent laminated object made of porous materials. CONSTITUTION: The laminated object includes a foam resin member(20) having an excellent shape keeping ability, and a peripheral frame(30) laminated to the back side of the foam resin member(20). The peripheral frame(30) has an L-shaped cross section having high strength. Also, a connection rib(40) for keeping the shape of the foam resin member(20) is installed between the peripheral frames(30). To manufacture the laminated object, a foam resin sheet is set in a mold, making sure that the shape of the foam resin sheet has a cavity shape of the mold. Then, a fused resin is injection molded inside the cavity, and the peripheral frame(30) and the connection rib(40) are laminated onto the rear surface of the foam resin member(20).
