<p><P>PROBLEM TO BE SOLVED: To provide a wiring board and an electric current detector for accurately detecting a potential difference in a shunt resistance and a detected electric current without being affected by soldering. <P>SOLUTION: Lands for thereon mounting rectangular faces of the shunt resistance on its both end parts comprise: lands 11 and 12 each having a rectangular portion and disposed at a prescribed space centering on a center line CL; and lands 13 and 14 whose areas are smaller than those of the lands 11 and 12, each disposed on one end part of the land 11 or 12, and connected to the lands 11 and 12, respectively. Wiring patterns for detecting the potential difference between the both end parts of the shunt resistance comprise: a wiring pattern 21 connected to the land 13 and led out from the land 13 toward the land 14; a wiring pattern 22 connected to the land 14 and led out from the land 14 toward the land 13; and wiring patterns 23 and 24 connected to the wiring patterns 21 and 22, respectively, and led out in one direction. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
