To provide a film material used in manufacturing process of a card object, which allows miniaturizing laminating equipment.

A film material 2, made to adhere to a sheet material on its post two-fold inner face, comprises a transparent film body and a first hot-melt adhesive 21 and a second hot-melt adhesive 22 respectively applied on one surface and the other surface of the film body. Respective adhesive strengths of the first hot-melt adhesive 21 and the second hot-melt adhesive 22 are set up so that the adhesive strength between two second members 20 through the second hot-melt adhesive 22 becomes weaker than the adhesive strength between a first member 10 and the second member 20 through the first hot-melt adhesive 21; provided a card body is manufactured by adhering two inner faces of the second member 20, while lapping the second member 20 to the inner face of the first member 10; wherein the second member 20 corresponds to the film body of the film material 2, and the first member 10 is made into two-fold from a sheet form.
