CARD-TYPE ELECTRONIC DEVICE CAPABLE OF SUPPRESSING RISE IN TEMPERATURE, SLOT IN WHICH AND FROM WHICH A CARD-TYPE ELECTRONIC DEVICE IS INSERTED AND REMOVED, AND ELECTRONIC APPARATUS COMPRISING THE CARD-TYPE ELECTRONIC DEVICE AND THE SLOT

摘要

A card-type electronic device capable of suppressing a rise in the temperature of signal lines for high-speed communication requiring impedance control while ensuring sufficient thermal connection and electrical connection. A connector is fixed to a substrate on which electronic components that generate heat are mounted, and includes electrical contacts electrically connected to an external apparatus and a thermal contact thermally connected to the external apparatus. A cutout is formed in the substrate between a portion to which the thermal contact is fixed and a portion to which the electrical contacts are fixed.
