Magnetic sensor and method of manufacturing magnetic sensor

Abstract

To suppress the occurrence of problems due to the shape of a side face of a magnetoresistance effect element arranged on an inclined surface.SOLUTION: A magnetic sensor 1 comprises a substrate 301, a support member 310 having an inclined surface 310e, and an MR element 50 arranged on the inclined surface 310e. The MR element 50 has a bottom surface 50a, a top surface 50b, and a first side surface 50c and a second side surface 50d. The first side surface 50c is, as compared to the second side surface 50d, located in front in a first direction D1 that is along the inclined surface 310e and that gets close to the top surface 301a of the substrate 301. At least a part of the first side surface 50c is, as compared to a first virtual plane PL1, located close to the second side surface 50d, and the first virtual plane PL1 intersects with a first corner Ed1 present at a position where the top surface 50b and the first side surface 50c intersect and is perpendicular to the top surface 301a of the substrate 301.SELECTED DRAWING: Figure 13
