PROBLEM TO BE SOLVED: To provide an improved method of cooling an electric component mounted on a printed circuit board. SOLUTION: The printed circuit board is provided with a through hole 6 between an upper side 3 and a lower side 7 of the board main body, and is provided with at least one electric component 2 installed in the upper side 3, and at least one thermally conductive member 8 inserted into the through hole 6, extending from the upper side 3 to the lower side 7 and thermally combined with the electric component 2. The thermally conductive member 8 is provided with a flat upper part, and a lower part which is tapered or in which a recess is provided. COPYRIGHT: (C)2005,JPO&NCIPI |
