PROBLEM TO BE SOLVED: To improve the output characteristics of a spin valve thin film magnetic element and avoid side leading. SOLUTION: The spin valve thin film magnetic element has a laminate 16, a bias layer 17 and an electrode layer 18 having an overlay 18a and a relation shown by (Rsl/Hl)/(Rsg/Hg)<=0.02 where Hl is the length extending vertically inward from the surface of the electrode layer 18 facing a magnetic recording medium, Rsl is a sheet resistance of this layer 18, Hg is the length extending vertically inward from the surface of the laminate 16 facing the magnetic recording medium, i.e., the element height, and Rsg is a sheet resistance of the laminate 16. |
