Abstract
A light-emitting apparatus that improves the use efficiency of emission light from light-emitting elements by an optical element for light collection and improves the light-emitting intensity in front of the apparatus without increasing the size of the apparatus, and its manufacturing method are provided. The light-emitting apparatus includes light-emitting elements, a substrate on which the light-emitting elements are mounted in a mounted region and a pair of electrodes for supplying power to the light-emitting elements is arranged around the mounted region, a sealing resin that contains a phosphor excited by emission light from the light-emitting elements and seals the light-emitting elements on the mounted region, and an optical element that is placed to cover the sealing resin with a lower end in contact with a flat region between the pair of electrodes and the sealing resin on the substrate and collects light emitted from the light-emitting elements through the sealing resin.
