To provide a method for manufacturing a ceramic member which can easily mold the member having a complicated three-dimensional curved surface at a high speed, and a method for molding ceramic powder.

This method for manufacturing a ceramic member comprises the steps of filling a granulated powder 3 previously prepared in composition in an extra-thin hollow plastic vessel (body 14 and upper cover 15) having elasticity and molded in shape and size previously on the basis of a molding margin in later steps wile vibrating it by an exciter 19, pressing it by upper and lower molds 18, 21, and then sealing it by a thermally pressing ring 23 under reduced pressure by a suction pump 22 via an air bleeding hole 15-2.
