PROBLEM TO BE SOLVED: To provide a magnetic sensor which can perform centering alignment of a magnetic resistance bridge circuit with high accuracy and in which a plurality of magnetic resistance bridge circuits can be produced at desired angles. ! SOLUTION: The magnetic sensor comprises: a substrate 2; and two magnetic resistance bridge circuits respectively including first MR elements 11, 21, second MR elements 12, 22, third MR elements 13, 23, and fourth MR elements 14, 24, which are magnetic resistance elements obtained by forming a magnetic resistance part 40 in a zig-zag manner. The two magnetic resistance bridge circuits constitute magnetic resistance bridge layers (a first MR bridge layer 10, a second MR bridge layer 20) by making, adjacent to each other, each one side of the first MR element 11, the second MR element 12, the third MR element 13 and the fourth MR element 14, and the first MR element 21, the second MR element 22, the third MR element 23 and the fourth MR element 24.
