PROBLEM TO BE SOLVED: To provide a compact reflection mirror for a warning lamp capable of radiating visible light in a lateral length manner.SOLUTION: A reflection mirror 11 for a warning lamp includes: an inward reflection mirror 41 that has a curve surface mirror 45 reflecting light emitted by a light source 23 toward a first direction 31 to be a forward irradiation direction; an outward reflection mirror 42 that is provided so as to surround the outside of the inward reflection mirror 41, and has a curve surface mirror 47 reflecting light emitted by the light source 23 toward the first direction 31; a central reflection mirror 43 that is provided on the optical path of the first direction 31, and has a planar mirror 50 reflecting part of light, reflected on the inward reflection mirror 41 and the outward reflection mirror 42 and radiated to the first direction 31, toward a lateral; and a lateral reflection mirror 44 that is provided so as to be adjacent to the lateral of the optical path of the outward reflection mirror 42, and has a planar mirror 52 radiating light, reflected on the central reflection mirror 43 and guided to the lateral, toward the first direction 31. |
