<p>In a structure for cooling an integrated circuit (IC) (2), a hollow cylindrical member (22) is mounted on a cold plate (5) and receives a heat conductor (3) therein. The heat conductor (3) is a cylindrical member which is closed by a flat plate at one end thereof. Silicone gel (4) fills a gap between the hollow cylindrical member (22) and the heat conductor (3) and allows the heat conductor (3) to move due to the elasticity thereof. When the cold plate (5) is fixed in place on the IC (2) which is mounted on a printed circuit board (1), the heat conductor (3) moves in matching relation to the height and inclination of the IC (2). As a result, the heat conductor (3) and IC (2) are brought into close contact with each other. A compound (6) intervenes between the heat conductor (3) and the IC (2) to enhance the close contact of the heat conductor (3) and IC (2). <IMAGE></p>
