A mounting board including a pair of patterned electrodes, a lower surface and an upper surface opposed thereto on which a substrate of an electronic component is to be mounted, a pass-through hole penetrating through the upper surface and the lower surface, and a peripheral side surface that defines the pass-through hole. The pass-through hole includes a plurality of penetrating grooves that are cut into the mounting board and penetrate through the upper and lower surfaces. The plurality of penetrating grooves electrically split the pair of patterned electrodes. The pair of patterned electrodes is partly positioned inside the peripheral side surface, and a connection portion connecting the at least one pair of patterned electrodes and at least one pair of patterned electrodes provided on the upper surface of the substrate of the electronic component is to be disposed inside the peripheral side surface that defines the pass-through hole.
