<p>PROBLEM TO BE SOLVED: To obtain a technique which can miniaturize an apparatus as a whole and measure a current more precisely and to obtain a technique which can measure the DC component of a current. SOLUTION: This current measuring apparatus 200 comprises a detecting unit 12 and a measuring unit 18. An electrical interconnection 22 is passed through the hollow part 14 of the detecting unit 12. A current flows in the electrical interconnection 22 to a load 16 from a power-supply device 10. A magnetoresistance element is embedded in the detecting unit 12. When a current flows, a magnetic field is generated, and the electric resistance value of the magnetoresistance element is changed.</p> |
