Claim:
1. A magnetoresistance effect element, comprising: a first shield; a second shield; a first side magnetic unit including a second side magnetic unit including a stacked body including a single first non-magnetic layer provided between the fifth magnetic layer and the first shield, the single first non-magnetic layer contacting the fifth magnetic layer and the first shield; a single second non-magnetic layer provided between the sixth magnetic layer and the second shield, the single second non-magnetic layer contacting the sixth magnetic layer and the second shield; and a hard bias unit provided between the first shield and the second shield to be arranged with the stacked body in a third direction intersecting the first direction and intersecting the second direction, a saturation magnetic flux density of the fifth magnetic layer being less than a saturation magnetic flux density of the sixth magnetic layer.
