<p>PROBLEM TO BE SOLVED: To provide an electric current detector of thin type easy in assembling, as to the current detector for detecting contactlessly an electric current flowing in a conductor by measuring the intensity of a magnetic field generated by the current. SOLUTION: The first magnetic substance plate 5 formed into a U-shaped plane, of which a connecting part 9 is bent in an arrow mark-Z direction so that a coupling part 7 and a gap part 8 in parallel to each other have a step difference in the Z-direction, and the second magnetic substance plate 6 having a plane shape of U-shape similar to the first plate 5, of which a connecting part 12 is bent in the arrow mark-Z direction so that a coupling part 10 and a gap part 11 in parallel to each other have a step difference in the Z-direction are welded mutually at the coupling part 7 and the coupling part 10, and the gap part 8 is overlapped with the gap part 11 so as to form a gap G.</p> |
