in a magnetic head slider having a horizontal type head element which floats on or comes into contact with a recording medium , in which a portion 32 of the slider including the head element can be moved in a minute range in the tracking direction and the loading and unloading direction and is supported by a stationary section 31 forming a slider body via a support spring 34 , a leading wire 22 drawn out from the head element 43 is formed in the process of manufacturing the slider so that the motions of the movable section 32 of a microactuator with respect to the stationary section 31 are not obstructed . the lead wire 22 drawn out from the head element 43 mounted on the movable section 32 is composed of a flexible lead wire 22 , the rigidity of which is lower than that of the support spring 34 , and a leading wire is drawn from the movable section to the stationary section so that the movement of the movable section with respect to the stationary section is not restricted .
