Abstract

PURPOSE:To prevent the damage of an IC module due to the deformation of a substrate, in an IC card wherein the IC module is fitted in the recessed part of a card substrate to be embedded therein, by setting the bonding strength of the card substrate, the depth of the recessed part, the gap distance between the inner peripheral wall of the recessed part and the outer peripheral wall of the IC module to specific relation. CONSTITUTION:In an IC card wherein an IC module 5 is fitted in the recessed part 7 provided to a card substrate 6 to be embedded therein, the recessed part 7 is constituted so that the relation of d>tsintheta is formed when the bending strength of the substrate 6 is set to theta, the depth of the recessed part 7 is set to (t) and the gap distance between the inner peripheral wall of the recessed part 7 and the outer peripheral wall of the IC module 5 is set to (d). As a result, even when the long or short side of the substrate 6 is deformed by bending stress, the inner peripheral wall of the recessed part 7 is prevented from coming into contact with the IC module 5 to press the same and the effect of bending stress is not transmitted to the IC module 5 and, therefore, the destruction or the flying-out of the IC module 5 can be prevented and the card can be used without damaging the aesthetic appearance of the card.

However, such an IC card is subjected to various bending moments during use. Therefore, if there is no gap between the IC module embedded and fitted in the recess of the card base material and the recess, when the card base material is bent by long-side bending or short-side bending, the end surface of the recess is When the IC module is pressed, there are defects such as destruction of the IC module, protrusion of the IC module, and popping out, and further, cracking of the mold, cracking of the film of the card base material, and elongation occur, and the function and performance of the IC module are remarkably increased. There were problems such as damage to the card and deterioration of the card appearance, reducing product value. The present invention is intended to eliminate these conventional drawbacks accurately so that the function of the IC module and the appearance of the card board are not damaged even when the card board is bent. It is an object of the present invention to provide an IC card that can be easily fixed to the standard position of the concave portion of the substrate and has a simple structure and at low cost.
