    Abstract: PROBLEM TO BE SOLVED: To provide a current sensor which requires only a small space and can be manufactured at low cost.SOLUTION: A current sensor 1 includes: a flat plastic housing 7 including an under surface 8, a top surface 9, an electric terminal 10, and a current conductor 11 through which a current to be measured flows; and a semiconductor chip 4 including two magnetic field sensors 5. Magnetic field elements at the positions of the two magnetic field sensors 5, which are detected by the two magnetic field sensors 5, indicate opposite directions. The semiconductor chip 4 is connected with the electric terminal 10 via a wire or by using a flip-chip structure. The current conductor 11 extends from one sidewall of the housing 7 to an opposing sidewall, and is flatly embedded in the under surface 8 of the housing 7, thereby being exposed on the under surface 8 of the housing 7. Surfaces of the semiconductor chip 4 and current conductor 11 which oppose each other are isolated from each other by an electric insulating layer 15.
