Abstract
A magnetic reluctance sensor can obtain a stable output without causing a curve around the center of an output waveform of an MR output even if the gap between an MR element and an MR magnet is narrowed. A stable output is obtained without causing a curve in an output waveform even if the facing interval 'g' between magnet means 2 and a magnetism-sensitive element 3 is decreased, by setting a magnetism-sensitive pattern width 'd' of the magnetism-sensitive element 3 to a value 0.3 to 1.0 times larger than a magnetic pole width .lambda. of the magnet means 2.
