PROBLEM TO BE SOLVED: To provide a spacer for roll to roll process which can manufacture an extremely thin strip type flake laminated board. SOLUTION: Volatile matter is removed by heat-treatment in the state that the strip type flake laminated board is rolled up. The surface of the spacer for roll to roll process is made to be a smooth surface (Rz value<1 mm), a roughening portion protruding from the surface of an opposite plane is installed respectively in the side along the two long sides of the surface of the opposite plane. When the strip type flake laminated board is rolled up, the roll to roll process is performed together with the spacer for roll to roll process, the volatile matter contained in the rolled up strip type flake laminated board is made to be capable of being exhausted from a channel which is formed by the recessed portion in the roughening portion installed in the both sides of the spacer for roll to roll process in the process of the heat treatment.
