Zusammenfassung:PROBLEM TO BE SOLVED: To provide a housing provided with proper strength, a heat-insulating effect, an effect as a buffer material against an impact and excellent appearance, since adhesives do not protrude without any strain, and capable of multicolor offset printing. SOLUTION: A support body (A) contains an extruded resin foamed sheet having 1.05-10 times of foaming magnification and 500-2,000μm of thickness. A biaxially oriented thermoplastic film as a base material layer (B ) and a uniaxially oriented film of thermoplastic resin containing 8-65wt.% of inorganic fine powder as a paper-like layer (B ) to form a double layer composite paper (B) having 30-300μm of thickness is integrally stuck to at least one surface of the support body (A). The surface of a laminated body sheet 2 with 530-2,300μm of thickness having the paper-like layer (B ) on the surface is subjected to emboss working.
