Zusammenfassung:	PURPOSE:To obtain an information recording card which is excellent in transferring property, fixing property, long-term using stability, and falsifying preventiveness by providing an ink absorptive and a lubricant layer on the surface of a card base. CONSTITUTION:A thickness of 10-30 microns of an ink absorptive and holding layer 3 is provided on a base 2, and a thickness of 5 microns or less of a lubricant layer 4 capable of preventing the staining of the ground texture and also of allowing the ink to pass is provided on the layer 3. The lubricant layer 4 is composed of nitro cellulose fine particles of a grain size of 5 microns or less, a nearly whitish solid lubricant particle, and a saturated polyester resin into which these fine particles are uniformly dispersed. The surface roughness is a maximum height of 3-7 and a central line average roughness of 0.8-1.5 microns, as specified by JIS-BO601. The preferred weight proportion of the nitro cellulose fine particles to the saturated polyester resin and also that of the solid lubricant particles to the nitro cellulose fine particles and saturated polyester resin are 0.5:1-1.5:1 and 0.3:1-2.0:1, respectively.
