Abstract
PURPOSE: To prevent a base material of a portable medium from being deformed caused by the heated IC module by inserting high thermal conductivity materials between a housing section on the base material and an IC module embedded in the housing. CONSTITUTION: A plurality of aluminum foils 4 comprising heat dissipation materials are between the bottom section of a chip housing channel 5 on a plastic card 3 comprising the base material, and an IC module 1 fitted on an insulating substrate 2 to be inserted in the chip housing channel 5. The heat released from the IC module 1 via a mold section 9 is more uniformly released via a surrounding wall of the chip housing channel 5 owing to the excellent thermal conductivity of the aluminum foil 4. The heat is made uniform in a space of the chip housing channel 5 by the excellent reflection characteristics of the aluminum foil 4. It is possible to prevent the local high temperature portion from being caused around the upper section of the IC housing section 5, which results in precluding the deformation of the plastic card 3.
