To provide a heat insulating door body for a refrigerator, which prevents deformation of outer appearance since partial separation of a steel plate and urethane is prevented, with respect to a structure of complicated shape such as a door face material having the curved shape.
The heat insulating door body is provided with hard urethane foam 4 between an inner case 3 and an outer case 2, and a latex adhesive agent obtained by diluting ethanol with a constant ratio is applied to a contact face of the outer case 2 and the hard urethane foam 4, thus the partial separation of the outer case and urethane is prevented in the structure of complicated shape such as the outer case 2 having the curved shape, and the heat insulating housing having good surface appearance is provided.
