PROBLEM TO BE SOLVED: To provide a mounting method of a current sensor easy-to-mount to a current bar enabling precise measurement of the current while removing the influences by external magnetic field.SOLUTION: The current sensor has a first sensor holding part 2 and a second sensor holding part 3, an extending direction thereof is parallel to an extending direction of a first current bar 11. The mounting method includes: a first step in which a current sensor mounting unit is positioned at a point where the first current bar 11 is sandwiched between the first sensor holding part 2 and the second sensor holding part 3; and a second step in which the current sensor mounting unit is rotated so that the extending direction of the first sensor holding part 2 and the second sensor holding part 3 is perpendicular to the extending direction of the first current bar 11 to nip the first current bar 11 with the first sensor holding part 2 and the second sensor holding part 3. |
