Patent abstract
An object is to provide a magnetic sensor permitting an increase in potential output. The magnetic sensor has a channel layer, a magnetization free layer provided on a first portion of the channel layer and configured to detect an external magnetic field, and a magnetization fixed layer provided on a second portion different from the first portion of the channel layer, and a cross-sectional area of the magnetization fixed layer in a surface opposed to the channel layer is larger than a cross-sectional area of the magnetization free layer in a surface opposed to the channel layer.
