A light-emitting diode 1 according to the present invention includes: a semiconductor light-emitting device 4 mounted on the surface of lead frames 2 and 3; and a transparent resin package 5 covering the front side of the semiconductor light-emitting device 4. A convex lens portion 8 for concentrating light emitted from the semiconductor light-emitting device 4 toward the front is provided in a surface part of the resin package 5. A circular flat portion 11 for diffusing light emitted from the semiconductor light-emitting device 4 toward the sides is provided in a part of the convex lens portion 8 intersecting the optical axis of the convex lens portion 8. Part of the convex lens portion 8 surrounding the circular flat portion 11 is a convex-lens side face. A recess 7 whose side wall is partly the convex-lens side face is provided to surround the convex lens portion. <IMAGE> <IMAGE> <IMAGE>
