<P>PROBLEM TO BE SOLVED: To provide a current detection circuit in which a difference in current detection accuracy between each of sets of resistances can be absorbed. <P>SOLUTION: In a current detection circuit, a plurality of sets of a shunt resistance and a sense resistance connected to the shunt resistance in parallel, which are provided in a current path, are arranged on a substrate corresponding to a plurality of current paths in which amounts of currents flowing therein have correlation, and each of currents flowing in each of the current paths is detected by using a shunt ratio between the shunt resistance and the sense resistor. In the current detection circuit, each of the shunt resistances and the sense resistances in each of the sets are arranged on the substrate so that temperature differences, which are generated between the shunt resistances and the sense resistances when current detection is performed for the current paths, become equal in each of the sets. <P>COPYRIGHT: (C)2012,JPO&INPIT |
