Abstract

In a power source control circuit module, switching regulator devices and a linear regulator device are mounted on a surface of a laminated body so as to be spaced from each other. In an interface between dielectric layers of the laminated body, first to fifth internal ground electrodes separated by an electrode non-formation portion are provided. The first, second, fourth, and fifth internal ground electrode are connected to the respective switching regulator devices. The third internal ground electrode is connected to the linear regulator device. The first to fifth internal ground electrodes are connected to respective different external ground terminals.
