Patent ID: 8217643

Claim:
A current detector, comprising: a U-shaped plate conductor composed of a first conductor that is folded in one portion in a longitudinal direction to have two parts parallel to and facing each other having a predetermined width therebetween, so as to compose a first looped current path in the first conductor, and a second conductor that is connected to the first conductor and folded in one portion in a longitudinal direction to have two parts parallel to and facing each other having a predetermined width therebetween, so as to compose a second looped current path in the second conductor; a first magneto-electric transducer that is placed between the two parts of the first conductor so that a magnetic sensing axis is parallel to a width direction of the first conductor, of which a length in a direction of the magnetic sensing axis is smaller than the width of the first conductor; and a second magneto-electric transducer that is placed between the two parts of the second conductor so that a magnetic sensing axis is parallel to a width direction of the second conductor, of which a length in a direction of the magnetic sensing axis is smaller than the width of the second conductor, the second magneto-electric transducer being connected in series to the first magneto-electric transducer, wherein the magnetic sensing axes of the first magneto-electric transducer and the second magneto-electric transducer are on a same axis.
