PURPOSE: A manufacturing method of a loess board for bed is provided to improve a quality of the board for bed by preventing a generation of crack during the manufacturing process with mixing loess which has an excellent cohesiveness in the charcoal powder. CONSTITUTION: A manufacturing method of a loess board for bed comprises the following steps. Dough is kneaded by mixing 5-10 parts by weight of water base on 100.0 of loess. The air which is included in the dough is stirred in a vacuum apparatus and the air is removed. The dough is molded to a plane type molded product while pressurizing the dough in which the air is removed. The plane type molded product is dried. The dried molded product is plasticized in the oven at 950-1200°C. A glaze is coated on the surface of the molded product which is plasticized. The dough which is kneaded by mixing 5-10 parts by weight of water base on 100.0 of loess is further includes 10-50 parts by weight of charcoal powder base on 100.0 of loess. The dough which is kneaded by mixing 5-10 parts by weight of water base on 100.0 of loess is further includes 1-30 parts by weight of more than one which is selected from Chrysanthemum zawadskii var. latilobum as a form of powder, peppermint, cnidium, Korean angelica root or wormwood base on 100.0 of loess.
