Current sensor

A current sensor comprising:

• a first current path serving as a measurement-subject current path;
• a second current path provided in a vicinity of the first current path;
• and
• wherein each of the first and second current paths includes:
• a first conductive portion;
• a second conductive portion extending along an X direction from one end of the first conductive portion;
• and
• a third conductive portion extending along the X direction from another end of the first conductive portion,
• wherein the first and second current paths are apart in a Y direction orthogonal to the X direction,
• wherein the second and third conductive portions of the first current path are apart from each other in a Z direction and aligned with each other in the Y direction, the Z direction being orthogonal to the X and Y directions,
• wherein the second and third conductive portions of the second current path are apart from each other in the Z direction, and aligned with each other in the Y direction,
• wherein the current sensor further comprises first and second magnetoelectric conversion elements arranged with the first conductive portion of the first current path interposed therebetween, the first and second magnetoelectric conversion elements having a respective sensitive axis along the Y direction,
• wherein the second conductive portion of the second current path is arranged on one side of the first and second magnetoelectric conversion elements in the Y direction, and
• wherein a perpendicular line from a center line of the second conductive portion of the second current path to the first magnetoelectric conversion element and a perpendicular line from the center line of the second conductive portion of the second current path to the second magnetoelectric conversion element have a same direction and a same length.
