<p>PURPOSE:To easily form a recessed part and to protect a sheet layer from holding by fitting a fitting article such as an IC module in the recessed part of a card formed in order to preliminarily provide a release layer patternwise so as to leave the same to the peripheral edge part of the recessed part. CONSTITUTION:As a card material, a center sheet 2, a printing sheet 3 having arbitrary characters or patterns applied to both surfaces thereof and a transparent over-sheet 4 are successively superposed. A release layer 7 slightly larger than the bottom area of a recessed part to be formed and composed of a solid part 5 and the pattern part 6 of the peripheral edge part thereof is formed to the single surface of the center sheet 2 at a predetermined position and cured, dried, thermally fused and integrated. A slit having a predetermined size is formed to the release layer 7 of the card material 15 at the position of the solid part thereof and a release part is removed along with the solid part of the release layer 7 in a semi-punched state to form a recessed part 13 to obtain a card base material 16. Further, an adhesive 8 is supplied to the bottom part of the recessed part 13 and a fitting article such as an IC module is fitted in said recessed part to obtain a card 12.</p> |
