In a slider using thermal expansion type, being adjustable on a flying height thereof, having problems to be solved, i.e., to reduce the electric power consumption, and to lesson the heat load upon a reproducing element thereof, wherein a heating device 4 is located separating from tip portions of the recording and reproducing elements 2 and 3 . Also, for deforming only the vicinity of the heating device 4 and the recording and reproducing elements 2 and 3 , so as to protrude from, the heating device 4 and the recording and reproducing elements 2 and 3 are surrounded by a resin film 6 of small rigidity, thereby increasing an amount of protrusion of the recording and reproducing elements 2 and 3 per a unit of electric power, but without increasing temperature of the reproducing element 3 , with an aim of the structure of cutting off the force from materials of circumferences against the deformation.
