There is provided a magnetoresistance effect element which is capable of causing a large sense current to flow between electrodes and which has a smaller dispersion in direction of magnetization of a CPP element based on a magnetic field due to the sense current and has a lager reproducing output, and a method for producing the same. The magnetoresistance effect element is produced by: after forming a first electrode, forming a magnetoresistance effect film on the first electrode; applying a self-condensing organic resist on the magnetoresistance effect film, and thereafter, causing the organic resist to be droplets; subsequently, forming an insulating film thereon, and thereafter, removing the organic resist to form a groove portion in the insulating film to expose the top surface of the magnetoresistance effect film; and filling the groove portion with an electrode material to form a second electrode.
