PROBLEM TO BE SOLVED: To provide a magnetoresistive effect element of large magnetoresistance variation and stable characteristic by smoothly forming a magnetoresistive effect film even on a protruding part of a lower electrode, related to a current perpendicular to plane-magnetoresistive effect element, and to provide a method for manufacturing the element, a magnetic head and a magnetic reproducing device using the magnetoresistive effect element. SOLUTION: The magnetoresistive effect element comprises a lower electrode (2a) having a protruding part (P) protruding upward, an insulating layer (3a) that is so provided as to enclose the protruding part, a smoothed conductive layer (5) whose top surface is almost smoothly formed while burying unevenness caused on the protruding part and the surface of the insulating layer around it, a magnetoresistive effect film (6) laminated on the almost smooth top surface (5B) of the smoothed conductive layer, and an upper electrode (2b) provided on the magnetoresistive effect film.
