[Solution] A cover member 1 is an integrally molded article made of urethane foam and comprises an outside portion 3, an inside portion 4, and a joining portion. The outside portion 3 is a portion on the outside including an outer surface 6 of the cover member 1, and has a closed-cell structure with a low foaming rate. The inside portion 4 is positioned on a rear side of the outside portion 3 and has an open-cell structure with a high foaming rate. A plurality of holes 7 whereof an opening on one end side faces the internal combustion engine 2 are formed on the inside portion 4. The joining portion 5 constitutes a portion which is bonded to the internal combustion engine 2 when the 20 cover member 1 is mounted on the internal combustion engine 2, and is positioned on the rear side of the outer periphery of the outside portion 3 and comprises a closed-cell structure with a high foaming rate.
