<P>PROBLEM TO BE SOLVED: To provide a current sensor which can cope even with a large current and has high detection accuracy. <P>SOLUTION: A current sensor 12 is disposed close to a current line 11 and measures the current flowing through the current line 11 by detecting the magnetic field to be measured which is generated by the current flowing through the current line 11. The current sensor 12 is composed of a magnetic detection part 13 which detects the magnetic field to be measured and a case 14 in which this magnetic detection part 13 is stored, and includes a thermal conductive sheet 15 which is led out to the external surface of the case 14 from the inside of the case 14 between the magnetic detection part 13 and the current line 11. By this constitution, the temperature rise of the magnetic detection part 13 can be suppressed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
