There is provided the IC card including the card base material formed by stacking at least one or more layers of white or light-permeable core materials and one or more layers of white or light-permeable outer package base materials, and an IC module having at least an external connection terminal and an IC chip connected to the external connection terminal. The IC card is characterized in having a surface chromatic layer at least in an area including a periphery of an opening of a recessed part of the IC module on an outermost surface of the card base material and also having an intermediate chromatic layer between layers of the card base materials. The intermediate chromatic layer includes the opening of the recessed part at least in plan view, and is formed larger than the area of the opening part of the recessed part, which is formed penetrating the intermediate chromatic layer.
