PROBLEM TO BE SOLVED: To provide a manufacturing process of a backboard, which attains high accuracy in concave depth and excellent smoothness in concave bottom and allows price-reduction to address future thin-modeling, for an organic EL (electroluminescence) backboard. SOLUTION: The manufacturing process of a ceramic structure enables the transfer of a convexo-concave shape of a die on a laminated sheet of unsintered ceramic in a step to form a pressed lamination using the sheet of unsintered ceramic, wherein the transfer is carried out by using the die worked in a beforehand convexo-concave in front and back faces and laminating the sheet of unsintered ceramic on the die and pressing, in the production process of the ceramic structure.
