Abstract
An LED package used in a light-emitting device is provided with a function of position correction in mounting by self-alignment, and mounting density of such LED packages is increased. The LED package includes an LED element including an element electrode on a bottom surface, a phosphor layer containing a phosphor and covering a top surface and a side surface of the LED element, and an auxiliary electrode having an upper face bonded to a lower face of the element electrode, wherein the auxiliary electrode is larger than the element electrode, the auxiliary electrode includes a step that makes a lower face smaller than the upper face, and an end portion of the auxiliary electrode on a side where the step is formed is located inside an outer peripheral side of the phosphor layer.
