1. A process for manufacturing a ceramic circuit board, wherein at least dielectric ceramics and a conductor paste of base metal are co-fired, comprising the steps of:

  • preparing said conductor paste of base metal containing an organic material which is thermally decomposed at a temperature higher than a decomposition point of an organic binder contained in said dielectric ceramics;

    forming a circuit pattern of said conductor paste containing said organic material;

    thermally decomposing said organic binder in an oxidizing atmosphere at a temperature lower than said decomposition point of said organic material; and

    thermally decomposing said organic material in an atmosphere having a partial oxygen pressure lower than that of said oxidizing atmosphere.
