After a sacrifice layer 51 has been formed on a substrate 50, there are formed a protective layer 41, flying surface layer 42, head element layer 43 and actuator layer 44. Further, a slider body 45 is formed by means of plating, and then the sacrifice layer 51 is removed so that the slider body can be separated from the substrate 50. In the thus obtained magnetic head slider 40, when an actuator 40a is loaded or unloaded, a frictional force, generated when the head element 43 is made to come close to or contact with a recording medium, is reduced and the head element 43 can accurately follow a track on the recording medium. A portion of the head element layer 43 forms at least one protrusion 46 which protrudes from a surface opposed to the recording medium onto the recording medium side.
