Disclosed is a package substrate for an optical element, which includes a base substrate, a first circuit layer formed on the base substrate and including a mounting portion, an optical element mounted on the mounting portion, one or more trenches formed into a predetermined pattern around the mounting portion by removing portions of the first circuit layer so that the first circuit layer and the optical element are electrically connected to each other, and a fluorescent resin material applied on an area defined by the trenches so as to cover the optical element, and in which such trenches are formed on the first circuit layer so that the optical element and the first circuit layer are electrically connected to each other, thus maintaining the shape of the fluorescent resin material and obviating the need to form a via under the optical element. A method of manufacturing the package substrate for an optical element is also provided.
