PROBLEM TO BE SOLVED: To obtain light corresponding to a desired intensity distribution in a light-emitting device.SOLUTION: A light-emitting device includes: a protective cover 10 (cover) having light transmissivity; an LED package 22 (luminous body) that emits light L in an opposite direction from the protective cover 10; and a reflector 80 (reflection member) having a concave reflection surface 81 that is disposed opposite the protective cover 10 and reflects the light L emitted from the LED package 22 toward the protective cover 10. The concave reflection surface 81 is formed by combining a plurality of small reflection surfaces 81a. Each of the small reflection surfaces 81a has a plurality of radii of curvature. |
