<p>PROBLEM TO BE SOLVED: To provide a heat radiating structure of wiring pattern for large current, which can efficiently radiate the heat generated from the attaching sections of bus bar connecting terminals to a wiring pattern. SOLUTION: One 11a of a pair of sub-land sections 11a and 11b provided in parallel with an already existing paired land sections 4a and 4b in a wiring pattern 2, through which a large current flows is extended to the pattern 2 and, on the other hand, a sub-terminal 12 having the same shape as that of a bus bar connecting terminal 6 mounted across the land sections 4a and 4b is mounted across the sub-land sections 11a and 11b and used as a heat radiator by not connecting the terminal 12 to a bus bar 15. Therefore, the large quantity of heat generated from the connecting section between the terminal 6 and the already existing land section 4a can be radiated efficiently from the sub-terminal 12.</p> |
