PURPOSE: An electro magnetic field cutting off tile and its preparation method are provided to effectively cut off the electro magnetic filed generated from daily life, so that damage generated by the electromagnetic field is prevented. CONSTITUTION: The method comprises steps of: (i) after adhering a picture printed transfer paper(20) to a tile(10), heating the tile in an electric furnace at a temperature of over 900 deg.C for at least 2 hours and cooling it for 24-72 hours to deposit the transfer paper; (ii) after inserting the tile in a frame(50), forming each ceramic layer(60) on a rear side and side of the tile by pouring ceramic into the frame; (iii) coating the ceramic layer with copper powder; (iv) pouring resin in the copper powder layer(40) and heating the tile inserted frame in an electric furnace at a temperature of over 150 deg.C for 1-2 hours to form a resin layer(30); (v) cooling the frame for at least 24 hours and separating the tile from the frame.
