Abstract
A magnetic sensor includes an insulating layer including a protruding surface, a first MR element, and a second MR element. The protruding surface includes a first curved surface portion. The first curved surface portion includes a first portion including an upper end portion of the protruding surface, and a second portion continuous with the first portion at a position away from the upper end portion of the protruding surface. When the shape of the protruding surface is regarded as a function Z, the mean value of the absolute value of a second derivative Z″ of the function Z corresponding to the first portion is smaller than the mean value of the absolute value of the second derivative Z″ of the function Z corresponding to the second portion.
