Disclosed is a slider which is substantially rectangular and has a disc facing surface with an air inflow end and an air outflow end in the longitudinal direction, comprising a first positive pressure-generating section disposed near the air inflow end; a pair of second positive pressure-generating sections disposed separately in the breadth direction in an air outflow end side away from the first positive pressure-generating section; a negative pressure-generating section disposed in an air outflow end side from the first positive pressure-generating section; and a third positive pressure-generating section disposed in an air outflow end side from the negative pressure-generating section and has a maximum size, which is 25% or less of the longitudinal size, in the same direction as the longitudinal direction and a maximum size, which is 45% or more of the breadth size of the disc facing surface, in a direction perpendicular to the longitudinal direction.
