The present invention relates to a method of producing a zirconia ceramic case for a portable electronic device, wherein the case has a logo that is dramatically aesthetically enhanced. The logo is made of zirconia similarly to the zirconia case, and a composition of the logo is the same as that of the zirconia case with the exception of coloring additives. According to the present invention, a zirconia case sintering process, in which the zirconia case shrinks, is performed, and the same process is carried out for the logo, thereby preventing the shape of the logo from becoming warped, and achieving a dramatic aesthetic enhancement for the logo. |
