PURPOSE: A method for manufacturing hot rolled steel sheet of Ti added ferritic stainless steel having superior surface quality by minimizing skid button pressing degree due to creep deformation, increasing scale production amount to lower contact pressure and performing descaling before initial rolling to remove scale in pressed marks is provided. CONSTITUTION: In a method for manufacturing a hot rolled steel sheet by hot rolling the heated Ti added ferritic stainless steel slab after heating a Ti added ferritic stainless steel slab containing 0.3 wt.% or more of Ti in a reheating furnace, the method comprises a step of heating the steel slab to a heating temperature of 1,100 to 1,130 deg.C in the reheating furnace for 200 to 230 minutes; a step of extracting the heated steel slab from the reheating furnace; a step of descaling the extracted steel slab before performing the initial rolling operation; and a step of hot rolling the descaled steel slab, wherein the ferritic stainless steel comprises 0.3 wt.% or more of Ti, 11 to 16 wt.% of Cr and less than 0.5 wt.% of Ni.
