PROBLEM TO BE SOLVED: To especially provide a magnetic sensor and magnetic sensor module which is rationalized in arrangement of fixed resistance provided with a first soft magnetic material and a magnetoresistance effect element. SOLUTION: The fixed resistance elements 4, 5 are approximately serially arranged in a longitudinal direction (Y1-Y2 direction). The fixed resistance elements 4, 5 are composed of an element part 12 provided with a fixed magnetic layer, nonmagnetic layer and free magnetic layer and a first soft magnetic material 23 positioning above the elementary part 12. A fixed resistance element formation region 80 surrounding the fixed resistance elements 4, 5 and the magnetoresistance effective elements 2, 3 are opposing in a lateral direction (X1-X2 direction). In a region between the magnetoresistance effective elements 2, 3 and the fixed resistance element formation regent 80, a third soft magnetic material 71 is provided. The third soft magnetic material 71 is formed long in a longitudinally direction. COPYRIGHT: (C)2009,JPO&INPIT
