<p>PROBLEM TO BE SOLVED: To provide a current sensor achieving higher positional accuracy and manufacturing efficiency and a manufacturing method thereof.SOLUTION: A current sensor 1 comprises: an annular core 3, which has a gap G, through which a conductor 2 whose current is to be detected penetrates; a magnetic detection device 4 located in the gap G that detects the strength of a magnetic field in the core 3 resulting from the current flowing through the conductor 2; a first member 6 that joins the core 3 and the magnetic detection device 4 together; and a second member 7 that has a through-hole 7a in the direction opposite to the first member 6 and is integrated with a lead frame 71 having a bent lead wire 71a, which is bent in a hook shape, projecting from the through-hole 7a. A terminal 41 of the magnetic detection device 4 projects from the through-hole 7a, and the terminal 41 and the bent lead wire 71a are fixed.</p> |
