<p>PROBLEM TO BE SOLVED: To provide a current sensor that can be mounted even if an available space is small around a battery post or the like, that has good mounting workability, and that can reduce hysteresis.SOLUTION: A current sensor comprises: a current-conducting conductor 5 disposed inside first and second magnetic materials 2A, 2B; and a hole IC 6 as a magnetic sensing element. The current-conducting conductor 5 is formed with a through-hole 4 in a direction penetrating inside areas of the first and second magnetic materials 2A, 2B, to flow current in the direction penetrating the inside areas. A magnetic field generated by the current flowing in the current-conducting conductor 5 is applied to the hole IC 6.</p> |
