<p><P>PROBLEM TO BE SOLVED: To provide an inexpensively-manufacturable current sensor having small temperature dependency and a small change with time of a characteristic, and formed by arranging a magnetoelectric conversion element in a gap of a magnetic core. <P>SOLUTION: This current sensor 100 comprises a core storage case 10 formed by being insert-molded in a resin case 12 so that the ring-shaped magnetism collection core 11 having the gap 11g is exposed to an internal space 12b linked to one opening part 12a around the gap 11g; and an element holder 20 loaded with the magnetoelectric conversion element 21, and formed by being insert-molded so that terminal pins 22 connected to the magnetoelectric conversion element 21 are exposed from one end face of a resin holder 23. In the sensor 100, the magnetoelectric conversion element 21 is arranged in the gap 11g, and an element holder 20 is inserted and fixed into the core storage case 10 through the opening part 12a. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
