PROBLEM TO BE SOLVED: To provide a fixing structure of an electronic control unit, which can meet the various requirements for the heat dissipation capacity in an inexpensive configuration. SOLUTION: A stay member 2 comprises a flat plate-like parts 21a, 21b, 21c and a plurality of radiating fins 22 erected on one major surface side at both end parts of a plate-like part 21. In each stay member 2, the plate-like part 21 differs in shape and area by types. The stay members 2 of different shapes are stacked such that one major surface of a stay member of a small area of the plate-like part 21 comes into surface contact with the other major surface of a stay member of a large area of the plate-like part 21. According to such a constitution, it is possible to stack the stay member 2 with the radiating fin erected while keeping their mutual thermal conductivity high. COPYRIGHT: (C)2004,JPO |
