<P>PROBLEM TO BE SOLVED: To obtain a semiconductor device capable of improving current detection accuracy without increasing a chip area. <P>SOLUTION: A semiconductor element 1 has an emitter electrode 7. Lead wire 10 is electrically connected to the emitter electrode 7, passes above the emitter electrode 7 and is led out to a side. A current sensor 11 has a magnetoresistive element 12 and detects current flowing through the lead wire 10. The magnetoresistive element 12 is arranged on the emitter electrode 7 and below the lead wire 10. A resistance value of the magnetoresistive element 12 linearly changes relative to a magnetic field generated by the current. <P>COPYRIGHT: (C)2012,JPO&INPIT |
