<p>Provided is a technology of mass-producing conductive bodies, each of which has a current detection head fixed thereto, and has a stable relationship between a detection value and a current value, said current detection head detecting a value of a current flowing in the conductive body. The head is provided with a lens, a magnetooptical element, the conductive body, and a fixing member, and the lens, the magnetooptical element, and the conductive body are fixed to the fixing member. An optical system, wherein light is guided to the magnetooptical element through the lens by means of the current detection head, and light having been subjected to magnetooptical effects by means of the magnetooptical element is guided to the lens, is formed. Since all the members that relate to current detection are fixed to the fixing member, correlative positional relationships among all the members that relate to the current detection are uniquely determined, and the conductive bodies having less variance in current detection characteristics can be mass-produced. The conductive body may be obtained by forming, between the fixing member and the conductive body, a shape for determining the positional relationship between the fixing member and the conductive body, and by fixing the aligned current detection head and the conductive body.</p> |
