PROBLEM TO BE SOLVED: To provide a radiation mounting structure in which heat generated in a termination resistor on a printed board can be diffused via an outer cabinet. SOLUTION: A radiation block 4 where a radiation piece 2 and the lower side 3a of the termination resistor 3 is thermally conductively connected through the printed board 1 is formed, and the radiation block 4 is screwed to the desired part of the printed board 1 by screws 7. Thus, heat generated by heat generation of the termination resistor 3 is efficiently diffused via the radiation block 4, and parts can be arranged in desired places of the printed board 1. Thus, a high degree of freedom on layout design of the printed wiring board can be secured. COPYRIGHT: (C)2005,JPO&NCIPI
