Abstract:
1. A method of manufacturing a multilayer ceramic wiring board comprising the steps of: forming a wiring layer by printing conductive paste on an unfired green sheet; forming an adhesive layer on at least one face of a ceramic substrate, said adhesive layer comprising one of a thermoplastic resin and a thermosetting resin as a main component; forming a laminate by laminating said unfired green sheet having said wiring layer on said face of the ceramic substrate; firing said laminate so as to remove a binder resin in said green sheet and said adhesive layer; and sintering glass ceramic materials in said green sheet and conductive particles in said conductive paste onto said face of the ceramic substrate, wherein, after a burnout of said binder resin, said glass ceramic materials start to sinter, and one of upon and after start of sintering of said glass ceramic materials, said conductive particles start to sinter, wherein said conductive paste includes a plurality of resin components, each of the resin components has a burn-out temperature range having a variation of 140° C. to 250° C., and said plurality of resin components are burned out at a temperature of 200° C. to 450° C.
