PROBLEM TO BE SOLVED: To provide a manufacturing method of a magnetic sensor element, which prevents potential differences between a substrate, a lower shield layer, a magnetoresistive element, and an upper shield layer in the manufacturing process, and provide a magnetic sensor element. SOLUTION: The substrate (wafer) 1 has a lower shield layer 11, a lower gap layer (not illustrated), a magnetoresistive element 2 displaying magnetoresistive effects, an upper gap layer (not illustrated), and the upper shield layer 16. a pair of terminals (31 32) jointed to both ends of a magnetoresistive element 2 are electrically connected to a part 11a of the lower shield layer 11 or a part 16a of the upper shield layer 16. Further, the part 11a of the lower shield layer 11 is connected to a part 1a of the conductive substrate 1.
