A method for manufacturing a magneto-resistance effect element includes: forming a fixed magnetization layer; forming a free magnetization layer; and forming a spacer layer with an insulating layer and a non-magnetic metallic path penetrating through the insulating layer, includes: forming a first non-magnetic metallic layer; forming, a metallic layer on a surface of the first non-magnetic metallic layer; irradiating, onto the metallic layer, ions or plasma including at least one of oxygen and nitrogen and at least one selected from the group consisting of Ar, Xe, He, Ne, kr so as to convert the metallic layer into the insulating layer and the non-magnetic metallic path containing the first non-magnetic metallic layer; forming a second non-magnetic metallic layer on the non-magnetic metallic path; and irradiating ions or plasma onto at least one of the fixed magnetization layer, the first metallic layer, the metallic layer, the insulating layer converted from the second metallic layer and the second non-magnetic metallic layer.
