Abstract:
A magnetic sensor comprising:a magnet having an end face; anda detector unit having an integrated circuit, said integrated circuit having a magnetic detector unit, a processing circuit, and a filter all manufactured on one side of a substrate, said filter comprising one of a capacitor having an electrode and a resistor connected to a capacitor that has an electrode,wherein said magnetic detector unit has a magnetic field sensing element for outputting a signal in the form of a voltage change corresponding to a change in the magnetic field of said magnet, and wherein said processing circuit processes said signal output by said magnetic detector unit, and wherein said filter removes noise from said signal, and wherein said detector unit is disposed in close proximity to said end face of said magnet, and wherein said resistor is formed into a same structure as that of said magnetic field sensing element of said magnetic detector unit, and wherein said electrode of said capacitor is formed into a same structure as that of a first interconnecting conductor which connects the capacitor to the processing circuit.
