Abstract:
1. A magnetic detector comprising: a first magnetoresistance effect element layer having an electrical resistance which changes in response to an external magnetic field; a first resistance element layer connected in series to the first magnetoresistance effect element layer; a first short-circuit layer that is conductive, the first short-circuit layer forming a short-circuit path having a first short-circuit length; and a second short-circuit layer that is conductive, the second short-circuit layer forming a short-circuit path having a second short-circuit length, wherein the first short-circuit layer is disposed on and electrically connected to one of the first magnetoresistance effect element layer and the first resistance element layer, wherein the second short-circuit layer is disposed on and electrically connected to the other of the first magnetoresistance effect element layer, and wherein a difference between the first short-circuit length and the second short-circuit length adjusts a difference between the electrical resistance of the first magnetoresistance effect element layer and an electrical resistance of the first resistance element layer.
