Abstract

A magnetic sensor includes a substrate including a top surface, an insulating layer including an inclined surface, and a magnetic detection element disposed on the inclined surface. The magnetic detection element includes a first side surface and a second side surface. The first side surface is located at a position forward in a first direction that is one direction along the inclined surface. The second side surface is located at a position forward in a second direction that is another direction along the inclined surface. The magnetic detection element includes a first non-constant portion in which a gap between an upper end of the first side surface and an upper end of the second side surface becomes smaller along the longitudinal direction of the magnetic detection element.
