PROBLEM TO BE SOLVED: To provide a technique to improve accuracy in electric current measurement by accurately securing a relative position of a bus bar to a magneto-electric transducer in a bus bar module equipped with a current sensor in which a plurality of bus bars are placed in parallel.SOLUTION: A bus bar module 10 comprises: a first bus bar 2 and a second bus bar 3 that are placed in parallel; a first magneto-electric transducer 6a placed so as to face a side surface of the first bus bar 2; a second magneto-electric transducer 6b placed so as to face a side surface of the second bus bar 3; and a board 5. The first bus bar 2 is provided with a first notch 2a. The second bus bar 3 is provided with a second notch 3a in an extending direction of the first bus bar 2 and at a position different from the first notch 2a. The board 5 fits into both of the first notch 2a and second notch 3a, and is wedged between facing side surfaces of the first bus bar 2 and second bus bar 3. The board 5 maintains relative positions of the first bus bar 2, second bus bar 3, and magneto-electric transducers 6a, 6b. |
