<P>PROBLEM TO BE SOLVED: To provide a magnetic sensor and a magnetic sensor module, for efficiently improving a magnetic shield effect in a direction perpendicular to its sensitive axis especially. Ž<P>SOLUTION: The magnetic sensor includes magnetoresistive effective elements 2, 3, and the magnetoresistive effective elements 2, 3 have an element part 12 which brings out the magnetoresistive effect, and a soft magnetic material 18 is disposed on both sides of the element part 12 in the sensitive axis direction (Y-direction). Both the side ends 18b of the soft magnetic material 18 in the direction (X-direction) perpendicular to the sensitive axis direction, are positioned so as to elongate rather than the element part 12 in the perpendicular direction. The width dimension of both the side ends 18b is large in comparison with the width dimension of the soft magnetic material 18 except both of the side ends. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
