    摘要: A multilayer ceramic substrate includes a glass ceramic body, a conductive pattern, and a via conductor. The conductive pattern is formed in the glass ceramic body and on at least one principal surface of the glass ceramic body. The via conductor makes a connection between the predetermined conductive patterns. The via conductor includes a conductive material and a Mo compound or a Mo metal. The conductive material includes at least one selected from the group consisting of Ag, Au, Pt and Pd as a main component. The amount of Mo compound or Mo metal is in the range of 0.05 to 10 parts by weight in terms of Mo metal with respect to 100 parts by weight of the conductive material. This multilayer ceramic substrate can achieve sufficient flatness and high dimensional accuracy, while preventing defects that occurs in the vicinity of electrodes after firing.
