PROBLEM TO BE SOLVED: To provide an interior and exterior integrated wall material which is light in weight and high in strength by arranging a heat insulation material inside a basket body having a steel frame, and forming an interior wall and an exterior wall with the light-weight cement mortar on the external surface as a wall body for dwelling of wooden or light-weight steel structure. SOLUTION: A basket body is formed by combining an interior wall side rigid body to which a steel plate 4 having holes and projections is welded to a frame body formed of angles and reinforcement plates with an exterior wall side net body in which a reinforcement 7 is welded to a lath net 5, and a urethane foam 8 is arranged in the inner space as a heat insulation material. A pattern sheet 9 for decorating an exterior wall is loaded on a level block 10, an exterior wall side mold 11 is loaded thereon, and the light-weight cement mortar is placed so that the lath net 5 of the basket body is located at a center part in thickness as an exterior wall material. Then, an interior wall side mold 12 is loaded thereon, and the light-weight cement mortar to constitute the interior wall member is placed on the steel plate 4. An interior and exterior integrated wall material which is light in weight, excellent in fire resistance and heat resistance, high in strength, and unnecessary to provide a bracing.
