Current sensor

current sensor, comprising:

• a bus bar through which a current as a measuring object flows;
• a magnetic detection element that detects a magnetic field intensity generated by the current flowing in the bus bar;
• first and second shielding plates arranged so as to sandwich the bus bar between the first and second shielding plates in a thickness direction of the bus bar;
• a first conductive plate comprising a conductive nonmagnetic material, and arranged between the bus bar and the first shielding plate;
• and
• a second conductive plate comprising the conductive nonmagnetic material, and arranged between the bus bar and the second shielding plate,
• wherein the magnetic detection element is arranged closer to the first conductive plate with respect to a center of the bus bar in the thickness direction,
• wherein a distance between the first conductive plate and the bus bar is longer than a distance between the second conductive plate and the bus bar, and
• wherein the first conductive plate comprises a slit formed in the first conductive plate at an overlapping position with the magnetic detection element in the thickness direction, and pierces the first conductive plate in a thickness direction of the first conductive plate.
