<p>A current detector (100) has a magnetic core (108) having a structure in which two kinds of sheet cores (104, 106) whose easy magnetization directions are different from each other are laminated. By adopting such a laminate structure, the whole magnetic core (108) is capable of exhibiting good magnetic characteristics. An output voltage from a Hall element (110) exhibits good linearity with respect to a current to be detected. Further, unlike a conventional toroidal type core, man-hour and time which are required for processing are reduced, which accordingly can hold manufacturing cost down.</p> |
