Technical Examples
  1. Unfired first ceramic layers 11 and at least one unfired second ceramic layer 12 having a different color from the unfired first ceramic layers 11 are laminated to prepare an unfired ceramic laminate 13. Notches 14 are then formed on a surface of the unfired ceramic laminate 13 using the second ceramic layer 12 as a reference. The unfired ceramic laminate 13 is fired to provide a fired ceramic laminate 13a, which is then divided along the notches 14 into ceramic composites 13b. In this process, notches having the proper depth can be formed on the unfired ceramic laminate 13.
