CURRENT DETECTOR EQUIPPED WITH HALL ELEMENT

摘要

PROBLEM TO BE SOLVED: To solve such a problem that it is difficult to increase the sensitivity of a current detector using a Hall element while suppressing an increase in cost and dimension. SOLUTION: A semiconductor device 2 including the Hall element 13 is arranged along a U-shaped conductor 3 for forming a current path. A magnetic layer 4 comprising a permalloy is applied to the main surface 21 and outside surface 23 remote from the Hall element 13 of the conductor 3.
