Abstract

A magnetic sensor includes a magnetoresistive body that is disposed over a surface of an insulator, a protective film that is provided over a surface of the insulator, including over the magnetoresistive body, and an open portion that runs along at least a portion of a perimeter of the magnetoresistive body and penetrates the protective film in a thickness direction of the protective film. In the magnetic sensor, a separation distance between an inside wall of the open portion and the magnetoresistive body, this being a minimum distance with respect to the magnetoresistive body, is configured so as to be longer than an alignment margin dimension of the open portion with respect to the magnetoresistive body.
