The present invention provides a magnetic sensor suitable for high resolution and having high reliability by achieving stable output even at the occurrence of variations in a gap between a magnetic medium and the magnetic sensor, and a magnetic encoder using the magnetic sensor. The present invention uses a magnetoresistive element having magnetoresistive properties that satisfy the inequation, H10-50<H50-90, where H10-50 represents a magnetic field required for a resistance change from DeltaRx10% to DeltaRx50% with respect to a maximum amount of resistance change DeltaR on a magnetoresitance effect curve, and H50-90 represents a magnetic field required for a resistance change from DeltaRx50% to DeltaRx90%.
