PROBLEM TO BE SOLVED: To obtain a magnetoresistance effect element, wherein detected current can be effectively made to flow through three layers of a free magnetic layer/a non-magnetic conductive layer/a fixed magnetic layer which exhibit magnetoresistance effect and reproducing characteristics can be enhanced, and its manufacturing method. SOLUTION: A first antiferromagnetic layer 21 is formed utilizing an antiferromagnetic material having a specific resistance value higher than a conductive layer 22 and the conductive layer 22 is formed by being extended to a free magnetic layer 18 from the upper surface of the antiferromagnetic layer 21. Thereby, the shut of detected current from the conductive layer 22 to the first anti-ferromagnetic layer 21 can be suppressed and the detected current can be suitably made to flow through a multi-layered film 18 and output characteristics can be enhanced. |
