<p><P>PROBLEM TO BE SOLVED: To position highly accurately to a measuring object electric wire, a current sensor wherein especially an MI (magnetic impedance effect) element is used as a detection element. <P>SOLUTION: In the current sensor wherein two MI elements are provided in order to remove the influence of a disturbance noise and the difference thereof is utilized, it is considerably difficult to manufacture separately the two MI elements and to arrange them accurately on the determined positions. Hereby, a constitution is adopted, wherein the MI elements are manufactured as molded articles 5, 5 acquired by primary molding, packaged to acquire current measuring device 2, and installed on a printed board 4, to thereby simplify positioning. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
