PROBLEM TO BE SOLVED: To facilitate separation of a platelike material and enhance recyclability while specifying the adhesive strength of an internal member and a surface material and/or the adhesive strength of the internal member and a rear face material. SOLUTION: An adhesive 5 is applied to form a plurality of continuous lines on the rear face of an internal member 3. After a rear face material is placed on the adhesive 5, it is pressed through two rollers to stick the rear face material to the rear face of the internal member 3. Subsequently, the adhesive 5 is applied on the surface of the internal member 3 likewise to adhere the surface material. Instead of this, the adhesive 5 is applied on the rear face of the internal member 3 to form a plurality of continual lines. After the rear face material is adhered to the rear face of the internal member 3 likewise, the adhesive 5 is applied on the surface of the internal member 3 to form continual lines and to stick the surface material to the surface of the internal member 3. In this time, the adhesive strength of the internal member and the surface material and/or the adhesive strength of the internal member and the rear face material is set 0.01-3.0 kgf/cm2. In this way, the facing material and the internal member can be easily separated from each other and the waste can be separately recovered and the recyclability can be improved.
