Abstract
There are provided the steps of preparing a conductive foil and then forming a plurality of conductive paths by forming isolation trenches, which are shallower than a thickness of the conductive foil, in the conductive foil except at least areas serving as the conductive paths, fixing respective photo semiconductor chips ( ) to desired conductive paths, molding a light transparent resin ( ) serving as a lens to cover respective photo semiconductor chips ( ) individually and to fill the isolation trenches, and removing the conductive foil on the side on which the isolation trenches are not provided. Therefore, a light irradiating device ( ), in which back surfaces of the conduction paths can be connected to the outside to thus eliminate through holes and which has the good radiation characteristic, can be implemented.
