Abstract:
A process of producing an IC card, said IC card comprising a card substrate and an IC module embedded therein, said card substrate comprising a single core sheet and first and second cover films laminated over the core sheet on the opposite sides, said process comprising the steps of:(a) forming an adhesive layer on the inside of each of said first and second cover films while maintaining non-adhesive areas, formed at respective inner surfaces of said first and second cover films in which said IC module is to be fitted, free of any adhesive;(b) assembling said card substrate by bonding said cover films to the opposite sides of said core sheet by the interposition of said adhesive layers and hardening said adhesive layers;c) cutting said first cover film and said core sheet along the outer peripheries of said non-adhesive areas to form a cavity, wherein the cutting is carried out by a rotary cutter which includes a cutting edge formed therein along the outer periphery and a central relief portion having no cutting edge and formed in said rotary cutter about the rotational axis thereof; and(d) fitting said IC module into said cavity and fixedly securing said IC module to said card substrate.
