Abstract
A first insulating film is provided on a first shielding film. A magnetoresistive effective element is provided on the first insulating film. A first and a second leading conductor films are provided on the first insulating film and connected to both ends of the magnetoresistive effective element. A second insulating film covers the first and second leading conductor films and the magnetoresistive effective element, and a second shielding film is provided on the second insulating film. A terminal conductor for measurement is conductively connected to at least one of the first and the second shielding films, and exposed to a different surface of a slider from a medium opposing surface thereof.
