Abstract
Provided is a smart card that can improve the adhesive strength of the IC chip module even under low pressure, and can prevent deformation of the card by increasing the flowability of the conductive adhesive. The smart card includes a card bodywith an antenna coilbuilt in, and an IC chip moduleprovided with an antenna connection terminalfor conductive connection with the antenna coil, the IC chip modulebeing housed in an accommodating recessin the card body, wherein the antenna coiland the antenna connection terminalare conductively connected via a conductive adhesivein which conductive particlesare blended with binder resin, and the antenna connection terminalhas an openingwith a width larger than the average particle diameter of the conductive particles
