ABSTRACT:
A magnetic sensor. A plurality of sensing parts are deposited and formed on an element substrate in film form. The inside two of the sensing parts are connected in series to use for a reading of a narrow pitch magnetic pattern, and the outside two of the sensing parts are also connected in series to use for a reading of a wide pitch magnetic pattern. The connection of the sensing parts is carried out by using terminals and wires. The terminals are provided so as to short-circuit the ends of the sensing parts or for every sensing part.
