Abstract:
A method of producing a multi-layer ceramic substrate comprising a laminated member comprising a plurality of ceramic layers of a ceramic insulating material and a wiring conductor, and a passive component connected to the wiring conductor and stored in the laminated member, comprising the steps of:providing a compact block comprising a ceramic functional material adapted to become the passive component;providing a composite laminated member comprising a wiring conductor and plurality of laminated ceramic green sheets of a ceramic insulating material different from the ceramic functional material, said composite laminated member having an interior space adapted to receive the compact block;positioning said compact block in said space;after said positioning, positioning a sheet base, of a ceramic which does not sinter at the baking temperature of the composite laminated member and an oxidizable metal, on opposing principal planes of the composite laminated member at both ends with respect to the lamination direction of the raw composite laminated member;baking the resulting composite laminated member with the composite laminated member interposed between the sheet bases in an atmosphere containing oxygen; andthereafter eliminating the unsintered sheet bases.
