PROBLEM TO BE SOLVED: To provide a magnetic resistance effect element where an upper gap layer can be formed by reducing the current loss of sense current to a hard bias layer, preferentially making sense current flow to a sense area occupied in the center part of a multilayer film, improving reproduced output and securing appropriate insulating property. SOLUTION: An intermediate layer 21 formed of an insulating material or a high resistance material having a resistance value higher than that of an electrode layer 18 is arranged between a hard bias layer 17 and the electrode layer 18. The electrode layer 18 is formed by extending it onto a multilayer film 16. Thus, sense current to the hard bias layer 17 can be suppressed and sense current can directly be made to flow from the electrode layer 18 to the multilayer film 16. Thus, reproduction sensitivity can be improved and reproduced output can be improved.
