PROBLEM TO BE SOLVED: To increase an MR ratio by increasing the fixing force of a pinned layer and by increasing the contact area of a free layer with a nonmagnetic layer regarding a magnetoresistance effect element and a magnetic recorder. SOLUTION: As the free layer 4 in the magnetoresistance effect element comprising a laminated structure which is composed of an antiferromagnetic layer 1, the pinned layer 2, the nonmagnetic layer 3 and the free layer 4, a granular layer in which magnetic particles 5 are dispersed into a nonmagnetic matrix 6 is used. As the pinned layer 2, a single-phase ferromagnetic layer is used.
