Abstract
A power supply control IC is mounted on a surface of a multilayer body that defines a power supply control circuit module. A first inner-layer electrode connecting an inductor element and a switching regulator element for the power supply control IC, another first inner-layer electrode connecting the inductor element and a capacitor element, and still another first inner-layer electrode connecting the switching regulator element and the capacitor element are located on upper layer regions of the multilayer body and are routed in between a mounting area of the power supply control IC and a peripheral wall of the multilayer body. The first inner-layer electrodes have widths that are wider than those of second inner-layer electrodes which are located near a center region of the multilayer body and transmit control signals.
