PROBLEM TO BE SOLVED: To inhibit turbulence of an output of a magnetic sensor by an electric noise and to inhibit a fault and degradation of the magnetic sensor by an overvoltage. SOLUTION: A capacitor C1 and a resistor R1 are incorporated in series between a power source terminal of a Hall IC 10 and a grounding terminal in an electric circuit of a printed circuit board 11 connected with the Hall IC 10 as a magnetic sensor, a capacitor C2 is built in parallel with these, a capacitor C3 is incorporated between the grounding terminal of the Hall IC 10, and an output terminal, and a resistor R2 is built into a signal output line side of the output terminal. Thereby, turbulence of the output of the Hall IC 10 by the electric noise, the fault and the degradation of the Hall IC 10 by the overvoltage can be inhibited. COPYRIGHT: (C)2007,JPO&INPIT
