Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an IC card the outer appearance quality of which can be improved by reducing unevenness of an IC module surface, and a card material for the IC card.SOLUTION: The IC card includes: an IC module 10 which has a module substrate 20, an IC chip 30 fixed to a center part 20a of the module substrate 20 and mold resin 40 encapsulating the IC chip 30, the module substrate 20 including an attachment face 26, on a chip fixing face side of a periphery part outer than the mold resin 40; and a card base material 60 that has on a surface 61 side, a recessed part 70 housing the IC module 10. In a state where the IC module 10 is housed in the recessed part 70, and the attachment face 26 is attached to a mount face 76 facing the attachment face 26 out of the recessed part 70, the outer periphery part 20 of the module substrate 20 slants downward toward a center.
【課題】ICモジュール表面の凹凸を低減して、外観の品質を向上できるようにしたICカード及びICカード用のカード基材を提供する。【解決手段】モジュール基板20と、モジュール基板20の中央部20aに固定されたICチップ30と、ICチップ30を封止するモールド樹脂40とを有し、モジュール基板20のモールド樹脂40よりも外周部のICチップ固定面側に取付面26が設けられたICモジュール10と、ICモジュール10を収容する凹部70を表面61側に有するカード基材60と、を備える。ICモジュール10が凹部70に収容され、取付面26が凹部70のうち取付面26と対向する装着面76に取り付けられた状態で、モジュール基板20の外周部20bは中央に向かって下に傾斜している。【選択図】図4 |
