A method for manufacturing ink jet recording sheet having the steps, in that order, of: providing an under-coat layer on a polyolefin coating support having the center-line average roughness of the surface of the polyolefin coated support of 0.10 to 1.5 μm as measured at a reference length of 2.5 mm and a cutoff value of 0.8 mm; heating the polyolefin coated support on which the under-coat layer is provided; and coating on the under-coat layer a coating liquid that contains inorganic micro particles and binder so that the coating liquid forms a porous ink absorption layer, wherein the temperature difference between the temperature of the polyolefin coated support and the temperature of the coating liquid is within 15° C. in the coating step.
