A method for producing a curved ceramic sintered body is provided to secure good mechanical property by maintaining uniform density, strength, and sound wave velocity for each part of the ceramic sintered body. A method for producing a curved ceramic sintered body comprises the steps of: producing slurry by pouring the distilled water, ceramic powder, acrylamide as a monomer, methylenebisacrylamide as a dimer, and a dispersing agent into a ball mill and milling the materials for the certain time by balls; removing bubbles existing in the slurry, in a vacuum state; making a gel molding body by adding a reaction initiator and a catalyst to the slurry and injecting the slurry into a mold; molding the gel molding body in a curved form by drying the gel molding body in a curved drying jig; and sintering the curved gel molding body. Ceramic powder is one selected from a group comprising Al2O3(Alumina), B4C(Boron Carbide), Si3N4(Silicon Nitride), BN(Boron Nitride), SiC(Silicon Carbide), AIN(Aluminum Nitride), and ZrO2(Zirconia).
