ABSTRACT:
A multilayer ceramic substrate having high transverse strength, minimized warpage, and no delamination, has a laminated structure including an inner layer portion and surface layer portions, in which the thermal expansion coefficient of the surface layer portions is lower than the thermal expansion coefficient of the inner layer portion, the difference in thermal expansion coefficient between the surface layer portions and the inner layer portion is about 1.0 ppmK−1or more, and the weight content of a component common to both a material constituting the surface layer portions and a material constituting the inner layer portion is about 75% by weight or more.
