PURPOSE: Provided is natural leather having antimicrobial effect, which emits anions and far infrared rays, adsorbs and decomposes hazardous gas, and has deodorizing function, therefore, it can improve the health of users. CONSTITUTION: The natural leather is produced by a process comprising the steps of: spreading a first moisture-permeable resin, comprising 100wt% of a moisture-permeable resin, 2-10wt% of a hygroscopic material, and a very small amount of pigments, on the surface of raw natural leather(10) to form a stably bonded coating film(12); spreading a second moisture-permeable resin containing 6-12wt% of ceramic fine powder on the bonded coating film to form a functional coating film(14); forming a protection film on the surface of the second moisture-permeable resin by using an abrasion-resistant urethane resin. The moisture-permeable resin is condensation copolymers of ethylene vinyl acetate, acrylic acid or methacrylic acid, an ester, condensation copolymers of acryl ester and vinyl chloride or vinylidene chloride. And the hygroscopic material is at least one of silica, alumina-based activated carbon, zeolite, and porous ceramic.
