1. A method for manufacturing a magneto-resistance effect element, comprising steps of:
- 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 said insulating layer, comprising steps of;
forming a first non-magnetic metallic layer;
forming a metallic layer on a surface of said first non-magnetic metallic layer;
irradiating, onto said 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 said metallic layer into said insulating layer and said non-magnetic metallic path containing said first non-magnetic metallic layer;
forming a second non-magnetic metallic layer on said non-magnetic metallic path; and
irradiating ions or plasma onto said fixed magnetization layer.
