<P>PROBLEM TO BE SOLVED: To provide a highly reliable wiring board including a highly reliable conductor pattern, for which generation of cracks, disconnection and a short-circuit or the like is prevented. <P>SOLUTION: A manufacturing method of a wiring board of this invention includes: a step of preparing a sheet-like temporary compact constituted of a material containing a ceramic material and a binder; a step of obtaining a ceramic compact with a region containing a condensate of polyalcohol formed near a surface by imparting a composition containing the condensate of the polyalcohol to the temporary compact; a step of forming a conductor pattern precursor by discharging ink for conductor pattern formation containing metal particles and a dispersion medium in which the metal particles are dispersed by a droplet discharge method to the region containing the condensate of the polyalcohol of the ceramic compact; a step of obtaining a laminate by laminating the plurality of ceramic compacts; and a calcination step of calcining the laminate and obtaining the wiring board having a conductor pattern and a ceramic substrate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
