An ink jet recording material of the invention includes a polyolefin resin-covered paper substrate, an ink absorption layer and a layer principally including colloidal silica in this order at one face of the substrate, and a backcoat layer at an opposite face of the substrate. An MD direction Taber stiffness of the substrate is at least 3 mN&#xb7;m. The ink absorption layer principally includes fumed silica, and the backcoat layer is principally polyurethane resin. The ink absorption layer includes a thioether-based compound, and a polyolefin resin layer at a side of the substrate at which the ink absorption layer is to be provided includes an fluorescent brightening agent and a white pigment. A solid content coating amount of the colloidal silica is 0.05 to 0.3 g/m, and a solid content coating amount of the polyurethane resin is 0.8 to 1.5 g/m. A 20&#xb0; glossiness of a blank portion of a face of the recording material that features the ink absorption layer is 40 to 60%.
