Abstract
A magnetic sensor device may include 'A'-phase magnetic resistance pattern and 'B'-phase magnetic resistance pattern which are provided with a phase difference of 90° from each other; wherein the “A” pattern is provided with “+a” phase magnetic resistance pattern and “−a” phase magnetic resistance pattern with a phase difference of 180° from each other for detecting movement of a magnetic scale, and the “B” pattern is provided with “+b” phase magnetic resistance pattern and “−b” phase magnetic resistance pattern with a phase difference of 180° from each other for detecting movement of the magnetic scale, and the “+a” pattern, the “−a” pattern, the “+b” pattern and the “−b” pattern are formed on a same face of one piece of board so that the “+a” pattern and the “−a” pattern are diagonally located and the “+b” pattern and the “−b” pattern are diagonally located.
