PROBLEM TO BE SOLVED: To obtain a multilayer ceramic substrate capable of reducing the occurrence of silver migration from an electrode layer without reducing the mechanical strength, and a method for producing the same. A laminate obtained by laminating and firing a ceramic green sheet on which an electrode layer made of Ag is formed on a dielectric layer made of a glass ceramic material in which glass containing at least Si and Ca and alumina are mixed. It is a ceramic substrate, and the dielectric layer after firing contains anorthite (CaAl 2 Si 2 O 8 ) crystal phase and its crystal grain size is 84 nm or less. [Selection] Figure 1 |
