To prevent an asbestos board of a decorative laminate from hindering transit scattering its small pieces even though a car comes in contact with a side wall in a tunnel in the case where it is used for decoration and for protection thereon by a method wherein an elastic pressure sensitive adhesion sheet material is, in an interpositional manner, laminated between the asbestos board and a metal sheet.

A front face 1a of an asbestos board 1 for decoration is, for example, a decorative face colored in white or the like, an elastic pressure sensitive adhesion sheet material 2 of, for example, butyl rubber sheet of the like is stuck to a rear face 1b side of the asbestos board 1, laminated, and a decorative laminate A is formed by sticking a metal sheet 3 of a gallium steel sheet, a zinc steel sheet, an iron sheet etc., onto the rear face 2b side of the elastic pressure sensitive adhesion sheet material 2. By attaching the decorative laminate A to an inside wall of a tunnel, in addition to decoration of the wall face, the wall face is protected from impact caused by direct contact of the car or the like. Though the asbestos board 1 sometimes cracks, small pieces of the asbestos board 1 stick to the elastic pressure sensitive adhesion sheet material 2 as they are, do not scatter around, and labor for cleaning is not required.
