Abstract

Provided is a multilayer substrate that can prevent generation of cracks caused by stress generated due to a difference between the coefficient of linear expansion of electrode pads and that of a ceramic material. An electrode pad arranged on a layer below an outermost component mounting electrode pad has a larger area than an area of the component mounting electrode pad. Similarly, an electrode pad arranged on a layer below a component mounting electrode pad has a larger area than an area of the component mounting electrode pad, an electrode pad arranged on a layer below a component mounting electrode pad has a larger area than an area of the component mounting electrode pad, and an electrode pad arranged on a layer below a component mounting electrode pad has a larger area than an area of the component mounting electrode pad.
