摘要： A highly reliable ceramics substrate which can sufficiently secure a bonding strength of a surface conductor in an initial state and after a lapse of time (e.g., after a PCT) is provided. The multilayer ceramics substrate has a surface conductor on at least one surface of a multilayer body constituted by a plurality of laminated ceramics substrate layers. A reaction phase formed by a reaction between a ceramics component in the ceramics substrate layers and a glass component in the surface conductor is deposited at an interface between the surface conductor and ceramics substrate layers. For example, an alumina filler in the ceramics substrate layers and Zn in the surface conductor react with each other, thereby forming ZnAl2O4 as the reaction phase.

摘要： A multilayer ceramic substrate includes a plurality of stacked glass ceramic layers and internal conductors. The glass ceramic layers contain at least one diffusion element selected from the group consisting of Ti, Zr and Mn. The internal conductors contain Ag as a conductive material. The multilayer ceramic substrate is produced by the steps of adding at least one diffusion element selected from the group consisting of Ti, Zr and Mn to conductive paste and diffusing the diffusion element in the glass ceramic layers around the conductive paste. As a result, defects otherwise possibly generated around the internal conductors can be eliminated with exactitude.
