Claim:
1. A method of manufacturing a cover including a core made of a foamed material having heat insulating property, and a surface member for covering entire surfaces of the core, the surface member being made of a fiber reinforced plastic obtained by impregnating fibers with a resin, the method comprising: shaping the core comprising closed cells and the fibers by flexing an intermediate portion of the core to be elastically deformed under its own weight in a state in which the core is supported at two points corresponding to both end portions of the core on a molding die having a curved shape; impregnating the fibers with the resin by injecting the resin into a sealed space formed between the molding die and the core by vacuuming; and demolding the cover from the molding die after the resin is cured.
