<P>PROBLEM TO BE SOLVED: To provide a highly-reliable wiring board in which occurrence of a migration phenomenon is suppressed and occurrence of a conduction failure is prevented, and to provide a manufacturing method capable of efficiently manufacturing the wiring board. <P>SOLUTION: A manufacturing method of a wiring board comprises: a ceramic compact formation step of forming a plurality of ceramic compacts composed of a ceramic material and a material including a glass powder and a binder; a conductor pattern precursor formation step of forming a conductor pattern precursor on the ceramic compacts by discharging an ink for forming a conductor pattern including a metal particle, a dispersion medium in which the metal particle disperses, and an organic substance in a droplet discharge method; a lamination step of obtaining a laminate by laminating the plurality of the ceramic compacts on which the conductor pattern precursor is formed; and a sintering step of sintering the laminate under an atmosphere where an oxygen concentration is lower than or equal to 18%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
