<p>PROBLEM TO BE SOLVED: To prevent a projection being extended from the surface of one or a plurality of circuit elements from being formed in a ceramic multilayer wiring board, by printing one or a plurality of circuit element patterns onto the surface of a green sheet 20, that is formed by using a ceramics mixed material containing ceramic powder 2 and a binder resin, by using a conductor mixed material containing conductor powder 3 and the binder resin, composing a laminate by overlapping a plurality of green sheets 20 where one or pluralities of circuit element patterns are printed, and compressing and burning the laminate. SOLUTION: In the ceramic multilayer wiring board, an average particle diameter of the ceramics powder 2 is set to Rs, that of the conductor particle is set to Rd, and the standard deviation, if the distribution of the particle diameter of the conductor powder 3 is expressed by a normal distribution function, is set toσd, and the value of Rs is equal to or less than the value of (Rd-σd).</p> |
