To provide a molding process which allows a lamination member nicely occupying grooves of a laminating object despite using no tough-treating fluid member but a conveying support.

A laminating object 21 with a concave-convex surface of 0.2 mm or more flute width and 0.1-0.4 mm groove depth, a lamination member 20 and an elastic member 19 are put in this order and held tight between two conveying supports 17, 18 and are brought in a chamber 8; wherein the chamber 8 of a vacuum lamination device 1 is equipped with a suction means, a compression means and a heating means respectively on opposed open-and-shut surfaces of a top plate 2 and a floor plate 3. The chamber 8 is closed airtight, inside of the chamber 8 is vacuumed by the suction means, then the laminating object 21 and the lamination member 20 are compressed and heated by the compression means and the heating means through the conveying support 18 and the elastic member 19, thereby the molding is carried out so that the lamination member 20 would occupy inside the groove of the concave-convex face of laminating object 21.
