The present invention relates to a method for manufacturing a zirconia portable electronic device case having a logo having an excellent aesthetic. In the present invention, the logo is molded from zirconia as in the zirconia case, and its composition is made the same as the zirconia case except for the color additive. According to the present invention, during the sintering process of the zirconia case, the sintering shrinkage rate of the zirconia case and the sintering shrinkage rate of the logo may be the same, thereby preventing the shape of the logo from being warped and maintaining an excellent aesthetic appearance of the logo. |
