PROBLEM TO BE SOLVED: To solve the problem of a refrigerator employing an iron plate at the upper surface (bottom plate) of a machine room requiring waterproofness that an urethane foam molding can not be utilized as the bottom plate, for the purpose of reducing heat intruding into a compartment and recycling, because waterproofness can not be ensured. SOLUTION: Fine powder of urethane foam 1 and adhesive 3 are kneaded to produce a kneaded material 11 which is then injected into a hot press unit (die) arranged with a sheet 21 thus producing a planar molding 19 of 5-10 mm thick. The sheet 21 of the molding 19 is fixed to the upper surface (bottom plate) of a machine room while facing the machine room side and made of an olefin based plastic elastomer in order to reduce intrusion of heat into a compartment 41 through the bottom plate 33.
