Abstract: A light emitting device includes a mount board that includes a wiring pattern on an upper surface, and light emitting elements that are mounted at corresponding one of mounting positions on the wiring pattern to be connected in series and/or in parallel to each other through the wiring pattern. The light emitting elements each include a pair of electrodes on a back surface side thereof. The mounting positions include four or more connection terminals that are electrically separated from each other to connect the electrodes of their corresponding light emitting element to each other. Series connection and parallel connection numbers are determined in accordance with orientations of the light emitting elements in which each electrode straddles at least adjacent two of the four or more connection terminals that are spaced away from and adjacent to each other.
