PURPOSE:To make removal of a base material so easy by forming a damping layer with such a raw material as separable up and down at a time when the roof lining base material made up of laminating a cell-like structural support layer and a covered layer on a decorative layer is fixed close to a rood panel via the damping layer. CONSTITUTION:A roof lining base material 1 being attached to the underside of a roof panel P via a bonded layer 10 is formed into a support layer 2 and a laminated layer consisting of a covered layer 3 and a decorative layer 4, and a damping layer 5 is further laminated on top of this laminated body. The support layer 2 is formed into a cell-like structure from material of relatively thick paper corrugated board or the like, by way of example, while the covered layer 3 is formed from material such as a resin fiber or the like including resin felt or the like, and the decorative layer 4 from material such as tricot and nonwoven fabric or the like, respectively. In this case, the damping layer 5 is formed from a damping foam material separable up and down by dint of breaking force weaker than adhesive holding power of the bonded layer 10, whereby the base material 1 is made easily removable owing to separation in the damping layer 5. |
