Claim:
1. A printed circuit board comprising: a printed wiring board; a first electronic component having a first heat radiation pad; a first circuit component provided for the first electronic component and having a first terminal; a second electronic component having a second heat radiation pad and generating heat exhibiting a higher heat value than that of the first electronic component; a second circuit component provided for the second electronic component and having a second terminal; and a conductor provided on the printed wiring board and having a conductor pattern part, wherein the first electronic component, the first circuit component, the second electronic component, and the second circuit component are mounted on the printed wiring board, the first heat radiation pad of the first electronic component, the first terminal of the first circuit component, the second heat radiation pad of the second electronic component, and the second terminal of the second circuit component are connected through the conductor; and a thermal resistance between the second heat radiation pad and the first terminal is lower than a thermal resistance between the first heat radiation pad and the first terminal.
