Abstract:
A multilayer ceramic wiring board prepared from a plurality of sheets formed from a ceramic-incorporating material containing a ceramic powder and a binder resin and each having a pattern of one or a plurality of circuit elements printed on a surface thereof with use of a conductive mixture material containing an electrically conductive powder and a binder resin, by placing the sheets over one another to form a laminate, and compressing and firing the laminate, the multilayer wiring board wherein a mean particle size of the ceramic powder is not greater than a value of a mean particle size (Rd) of the conductive powder and less a standard deviation (ad) obtained when the distribution of the particle sizes of the conductive powder is expressed by a normal distribution function.
