<p><P>PROBLEM TO BE SOLVED: To provide a direct current sensor which has high accuracy and enables easy assembling with a minimum space, even when the current sensor cannot be inserted from the end of a primary conductor which is indivisible. <P>SOLUTION: A magnetic substance core having a gap is inserted to a core case, having a gap to which the primary conductor is inserted. A control circuit substrate part, mounted with a magnetic sensitive element, is inserted to a substrate case. These two cases have a irregularities and can be fastened mutually, and a position fixation can be carried out. The two cases which are composed with an integrable structure can be divided arbitrarily. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
