Current sensor

A current sensor comprising:

• a primary conductor through which a current to be measured flows;
• and
• a first magnetic sensor and a second magnetic sensor that each detects an intensity of a magnetic field generated by the current flowing through the primary conductor;
• wherein
• the current is diverted into first and second flow channels and flows through the primary conductor in a length direction of the primary conductor;
• the primary conductor includes an arch portion that extends in the length direction and bends to project in a first thickness direction of the primary conductor, and defines the first flow channel;
• the first magnetic sensor and the second magnetic sensor are arranged in a width direction of the primary conductor;
• the first magnetic sensor is disposed on an inner side of the arch portion and is located on a side of an undersurface of the primary conductor;
• the second magnetic sensor is located on a side of a surface of a portion of the primary conductor which defines the second flow channel;
• and
• each of the first magnetic sensor and the second magnetic sensor detects a magnetic field in the width direction.
