Abstract:
1. A method for manufacturing a fired ceramic body including a metal coil in its inside comprising the steps of: a first step of preparing said metal coil, preparing a mold having a space for storing said metal coil, and placing said metal coil in said mold; a second step of filling said mold with a ceramic slurry having a heat-gelling characteristic or a thermoset characteristic; a third step of forming a ceramic-compact-before-fired including said metal coil in its inside by hardening and drying said ceramic slurry in said mold; and a fourth step of firing said ceramic-compact-before-fired; wherein, said fourth step including steps of: wherein said second temperature increasing rate is higher than said first temperature increasing rate, wherein said metal coil is formed of one of a metal wire and an alloy wire that is helically wound and on which one or more films for suppressing at least one of effusion and diffusion of said metal or said alloy during firing.
