A light emitting device (100) includes a substrate (30) elongated in a lengthwise direction; a plurality of LED chips (101) disposed on the substrate (30) in an intermediate region in widthwise direction, and aligned along the lengthwise direction at a distance of 80 µm or less; and interconnection wirings (11) formed on regions outside the intermediate region in the widthwise direction; wherein each of the LED chips (101) has a p-side electrode (12) disposed on the substrate (30), a p-type semiconductor layer (23) disposed on the p-side electrode, an active layer (22) formed on the p-type semiconductor layer (23), and an n-type semiconductor layer (21) formed on the active layer (22), and has a region in which the n-type semiconductor layer (21), the active layer (22), and the p-type semiconductor layer (23) are patterned, and an n-side electrode (8) formed selectively on a surface of the n-type semiconductor layer (21) and connected to the p-side electrode (23) of an adjacent LED chip (101) through the interconnection wiring (11).
