A method of producing light emitting elements includes providing a wafer that includes a growth substrate and a semiconductor structure formed on the growth substrate, a lower side of the wafer being a growth substrate side, and an upper side of the wafer being a semiconductor structure side as an upper side; forming a separation groove in the wafer from the upper side of the wafer to demarcate portions of the semiconductor structure, the separation groove extending in a depth direction to a location in the wafer; forming a p-electrode and an n-electrode on an upper side of each of the demarcated portions of the semiconductor structure; forming a dielectric multilayer film at an upper side of the wafer, including portions defining the separation groove, by using an atomic layer deposition method; and separating the wafer into a plurality of light emitting elements by removing a portion of the wafer from a lower side of the wafer to at least the location to which the separation groove extends.
