Abstract:
1. A magnetic sensor comprising: a magnetoresistance element unit including meandering thin-film magnetoresistance elements; an IC circuit waveform processing unit including a comparator circuit and a feedback resistance, the magnetoresistance element unit and the IC circuit waveform processing unit being on a semiconductor substrate; the semiconductor substrate that is connected to both the magnetoresistance element unit and the IC circuit waveform processing unit; a first lead frame on which the semiconductor substrate is mounted, the semiconductor substrate and the first lead frame being included in a package, the first lead frame slopes against the surface of the package; and a pair of lead frames formed on either side of the first lead frame at a slope reciprocal to the slope of the first lead frame, the pair of lead frames structurally separate and connected by a wire to the first lead frame, wherein: the magnetoresistance element unit includes magnetoresistance elements that meander in different directions and forms a Wheatstone bridge.
