         11 . An ornamental steel plate according to  claim 1 , wherein the pattern forming material consists of a mixture of the synthetic resin, metal powder and stone powder.  
     
     
         12 . An ornamental steel plate according to  claim 11 , wherein the pattern forming material consists of a mixture of the synthetic resin and the metal powder or a mixture of the synthetic resin and the stone powder.  
     
     
         13 . An ornamental steel plate according to  claim 11 , wherein a pearl material is used as the pattern forming material instead of the synthetic resin.  
     
     
         14 . A method for manufacturing an ornamental steel plate, comprising the steps of: 
 coating an etching resist ink on a surface of a steel plate except for a pattern to be expressed;    drying the etching resist ink by heating;    forming a pattern forming groove by etching the pattern by spraying an etching solution on the surface of the steel plate;    removing the etching resist ink by spraying an etching resist ink remover on the surface of the steel plate; and    filling the pattern forming material having different texture and color from the steel plate in the pattern forming groove.    
     
     
         15 . A method according to  claim 14 , further comprising a step of removing a protruding portion of the pattern forming material on the steel plate and polishing the surface of the steel plate at the same time.  
     
     
         16 . A method according to  claim 14 , further comprising a step of forming a decal unit by fixing and heat-compressing the decal paper to the surface of the polished pattern forming material, and decalling the colors and patterns of the decal paper thereon.  
     
     
         17 . A method according to  claim 16 , wherein decalling is carried out on the entire surface of the pattern forming material.  
     
     
         18 . A method according to  claim 16 , wherein decalling is partially carried out on the surface of the pattern forming material.  
     
     
         19 . A method according to  claim 14 , wherein the etching resist ink is an acid proof ink.
