Abstract

In a detector apparatus, a first magnetosensitive unit includes first and third magnetic resistor elements arranged next to each other in a moving direction of the to-be-detected unit and electrically connected in series between a first potential and a second potential, a second magnetosensitive unit includes second and fourth magnetic resistor elements arranged next to each other in the moving direction of the to-be-detected unit and electrically connected in series between the first potential and the second potential, and as for resistances for a same magnetic field, a relation of whether or not a resistance of the third magnetic resistor element is higher than a resistance of the first magnetic resistor element is the same as a relation of whether or not a resistance of the second magnetic resistor element is higher than a resistance of the fourth magnetic resistor element.
