To provide a suitability as a vehicular headlight, and to eliminate color uneveness at lighting of LEDs.
A reflector 2 is composed by arranging two first reflecting surfaces 3a side by side. The two first reflecting surfaces 3a, 3a are arranged side by side by separating first focal points F1 thereof from each other around an optical axis Z within the range of the effective radius R of a convex lens 6 and by gradually bringing second focal points F2 thereof close to each other inside the two first focal points F1; and two LEDs 1, 1 are respectively arranged in the vicinity of the first focal point F positions by facing emission parts 1a to the respective two first reflecting surfaces 3a, 3a. The light distribution pattern provided has twice the light amount and will not have non-emission part therein and light is obtained by totalizing the light emission of the two LEDs 1, whereby color uneveness can be eliminated.
