Filing date: 2012-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic sensor capable of suppressing variation on working points.SOLUTION: A magnetic sensor 1 includes a serial circuit 9 configured by serially connecting first and second magneto-resistive elements R1 and R2. A power supply voltage Vcc is applied to the serial circuit 9. The first magneto-resistive element R1 and the second magneto-resistive element R2 are serially connected via an electrode pad 4 for taking out an output voltage Vout. The electrode pad 4 and the first magneto-resistive element R1 are electrically connected to each other via a first wiring pattern 3A. The electrode pad 4 and the second magneto-resistive element R2 are electrically connected to each other by a second wiring pattern 3B. The first wiring pattern 3A and the second wiring pattern 3B are formed separately from each other.
