Abstract
A magnetic sensor senses a magnetic field in a predetermined magnetic sensing direction. The magnetic sensor includes a chip on which at least one magnetic device is provided. The length of the chip in the magnetic sensing direction is twice or more the length of the chip in an orthogonal direction that is orthogonal or substantially orthogonal to the magnetic sensing direction.

A current sensor comprising:
- a magnetic sensor to sense a magnetic field in a predetermined magnetic sensing direction, the magnetic sensor including:
- a chip on which at least one magnetic device is provided;
- and a conductor to which the magnetic sensor is attached, the conductor a current to flow therethrough;
- wherein a length of the chip in the magnetic sensing direction is about twice or more than a length of the chip in an orthogonal direction that is orthogonal or substantially orthogonal to the magnetic sensing direction;
- the magnetic sensor senses a magnetic field produced by the current;
- the conductor includes two channels that allow the current to flow therethrough;
- wherein the two channels are offset from one another in the magnetic sensing direction and the at least one magnetic device is located between the two channels of the conductor.
