Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adiabatic door which prevents deterioration of adiabatic performance due to contraction of polyurethane foam.SOLUTION: A surface of a wood frame 20 is covered with a steel plate 30 to form a closed cavity 20a, the cavity 20a is filled with polyurethane foam 40 to form a core material 14, and the surface of the core material 14 is successively covered with a foaming phenol molding plate 50, a non-flammable plate 60, and a surface steel plate 70 to form a door body 14. Even when a space 15 is formed between the steel plate 30 and the polyurethane foam 40 due to contraction of the polyurethane foam 40, cooling air in a storage does not flow into the space 15, so that deterioration of the adiabatic performance is prevented.
