<p><P>PROBLEM TO BE SOLVED: To realize a cost reduction and a weight reduction while improving current detection precision. <P>SOLUTION: The magnetic yoke 1 is formed in an ended annular-shape, where a microscopic air gap 1a is formed. This magnetic yoke 1, where a current carrier 2 allowing a current to be measured to flow, penetrates into the center of a space, is to form a magnetic path allowing magnetic fluxes generated by the current to flow. A magnetic sensor 3 is arranged in the air gap 1a of the magnetic yoke 1. This magnetic sensor 3 is constituted of, for example, the bare chip of a Hall sensor chip, and fixed to the ends of the magnetic yoke 1 in the air gap 1a by adhesion. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
