A vehicle lamp comprising: a first lamp unit comprising a first light source and a first reflector configured to diffusely reflect the light from the first light source in vertical and lateral directions, when installed in a vehicle, around a lamp front direction, wherein a reflective surface of the first reflector has a bilaterally symmetrical shape in a vertical surface including an axis (Ax) parallel to the lamp front direction, and a second lamp unit comprising a second light source and a second reflector, wherein the first lamp unit and the second lamp unit are arranged side by side in such a way that the second lamp unit is provided on the outside in a vehicle width direction, the second reflector is disposed so as to be positioned on the rear side of the first reflector, the first light source and the second light source are arranged at the same height position in a state where the light emitting surface thereof faces downward, wherein the second light source is displaced further rearward than the first light source, and wherein the first light source and the second light source are supported on a common substrate which is supported on a lamp body, characterized in that, the second reflector is configured to reflect the light from the second light source in the lamp front direction, wherein the first reflector is arranged below the first light source and the second reflector is arranged below the second light source, a reflective surface of the second reflector is formed so as to extend to the inside in the vehicle width direction up to a position of partially overlapping with a reflective surface of the first reflector, as seen from the front of the lamp, and a first overlapping portion (224Ba1) of the reflective surface of the second reflector, which overlaps with the reflective surface of the first reflector, is formed so as to reflect the light from the second light source toward the outside in the vehicle width direction. a first lamp unit comprising a first light source and a first reflector configured to diffusely reflect the light from the first light source in vertical and lateral directions, when installed in a vehicle, around a lamp front direction, wherein a reflective surface of the first reflector has a bilaterally symmetrical shape in a vertical surface including an axis (Ax) parallel to the lamp front direction, and a second lamp unit comprising a second light source and a second reflector, wherein the first lamp unit and the second lamp unit are arranged side by side in such a way that the second lamp unit is provided on the outside in a vehicle width direction, the second reflector is disposed so as to be positioned on the rear side of the first reflector, the first light source and the second light source are arranged at the same height position in a state where the light emitting surface thereof faces downward, wherein the second light source is displaced further rearward than the first light source, and wherein the first light source and the second light source are supported on a common substrate which is supported on a lamp body, characterized in that, the second reflector is configured to reflect the light from the second light source in the lamp front direction, wherein the first reflector is arranged below the first light source and the second reflector is arranged below the second light source, a reflective surface of the second reflector is formed so as to extend to the inside in the vehicle width direction up to a position of partially overlapping with a reflective surface of the first reflector, as seen from the front of the lamp, and a first overlapping portion (224Ba1) of the reflective surface of the second reflector, which overlaps with the reflective surface of the first reflector, is formed so as to reflect the light from the second light source toward the outside in the vehicle width direction.
