A substrate module includes: a substrate having top and bottom surfaces and comprising, at the top surface, a plurality of first wiring regions and a plurality of second wiring regions that are electrically connected to the plurality of first wiring regions; one or more power receiving devices disposed on the plurality of first wiring regions; a first connection component disposed on the plurality of second wiring regions, wherein the first connection component has opposite ends in a first direction; and a protected component disposed on the top surface of the substrate. In a top plan view, (i) the protected component is located between two straight lines passing through the respective opposite ends of the first connection component and extending in a second direction perpendicular to the first direction, and (ii) the protected component is located between the one or more power receiving devices and the first connection component.
