Claim Text:
1. A current sensor comprising: a first magnetic sensor and a second magnetic sensor disposed around a current line such that the current line is positioned therebetween, the current line flowing a measurement target current therethrough, the first and second magnetic sensors detecting an induction magnetic field generated by the measurement target current the first magnetic sensor having a first main sensitivity axis and a first sub-sensitivity axis orthogonal to the first main sensitivity axis, and the second magnetic sensor having a second main sensitivity axis and a second sub-sensitivity axis orthogonal to the second main sensitivity axis, wherein the first magnetic sensor and the second magnetic sensor are placed such that the first main sensitivity axis is oriented in a direction not orthogonal to a direction of the induction magnetic field applied to the first magnetic sensor, and the second main sensitivity axis is oriented in a direction not orthogonal to a direction of the induction magnetic field applied to the second magnetic sensor, and wherein the first magnetic sensor and the second magnetic sensor are placed such that the direction of the first main sensitivity axis is the same as the direction of the second main sensitivity axis, and a directions of the first sub-sensitivity axis is the same as a direction of the second sub-sensitivity axis, or such that the direction of the first main sensitivity axis is opposite to the direction of the second main sensitivity axes, and the direction of the first sub-sensitivity axis is opposite to the direction of the second sub-sensitivity axis.
