发明名称 PC CARD
摘要 PROBLEM TO BE SOLVED: To radiate efficiently heat emitted from mounted parts by a method wherein a length of a PC card is made a length wherein its rear end is protruded from a card slot of a personal computer or the like, the mounted parts of a substrate is arranged at a rear end part, and the mounted parts are intensively bonded to a card box body with a heat conductive component. SOLUTION: A length of a PC card, when charged in a card slot 8 of a personal computer or the like, is a length wherein its rear end part 9 is protruded therefrom. Then, semiconductor elements 2 or the like are loaded intensively on a substrate 1 at the rear end part 9. A heat conductive sheet 7 consistinq of high heat conductivity material is made to lie between the semiconductor 2 and an inner face of the card box body 5 at the rear end part 9. Therefore heat generated in the mounted parts such as the semiconductor 2 or the like is transmitted to the rear end part 9 with the heat conductive sheet 7. Since the rear end part 9 is protruded from the card slot 8 when the PC card is charged in the card slot 8, its heat radiation to outside is efficiently carried out, and does not give an influence by radiation of heat on an inside of the personal computer or the like.
