A light-emitting module comprising: a light source unit comprising a plurality of light-emitting elements aligned in a horizontal direction, when installed in a vehicle; ; a projection lens receiving light emitted from the light source unit , and projecting the light through a light exiting surface of the projection lens in a radiation direction; and a frame body holding the light source unit and the projection lens at predetermined positions, wherein the projection lens comprises a first lens and a second lens each having the same focal length and the same curvature, the first lens and the second lens being disposed adjacently to each other in a vertical direction or as an integrated body, the first lens having a first light exiting surface with a first surface area and being at an upper position in the vertical direction, the second lens having a second light exiting surface with a second surface area and being at a lower position in the vertical direction, characterized in that a second ratio of the second light exiting surface area to a light exiting surface area of the projection lens is larger than a first ratio of the first light exiting surface area to the light exiting surface area of the projection lens, an angle of an optical axis from the horizon of the first lens differs from an angle of an optical axis from the horizon of the second lens in the vertical direction of projection, and a value in the vertical direction of a horizontal-to-vertical ratio for a light-emitting area of the light-emitting elements is smaller than a value in the vertical direction of a horizontal-to-vertical ratio for a projected area projected from the projection lens. a light source unit comprising a plurality of light-emitting elements aligned in a horizontal direction, when installed in a vehicle; ; a projection lens receiving light emitted from the light source unit , and projecting the light through a light exiting surface of the projection lens in a radiation direction; and a frame body holding the light source unit and the projection lens at predetermined positions, wherein the projection lens comprises a first lens and a second lens each having the same focal length and the same curvature, the first lens and the second lens being disposed adjacently to each other in a vertical direction or as an integrated body, the first lens having a first light exiting surface with a first surface area and being at an upper position in the vertical direction, the second lens having a second light exiting surface with a second surface area and being at a lower position in the vertical direction, characterized in that a second ratio of the second light exiting surface area to a light exiting surface area of the projection lens is larger than a first ratio of the first light exiting surface area to the light exiting surface area of the projection lens, an angle of an optical axis from the horizon of the first lens differs from an angle of an optical axis from the horizon of the second lens in the vertical direction of projection, and a value in the vertical direction of a horizontal-to-vertical ratio for a light-emitting area of the light-emitting elements is smaller than a value in the vertical direction of a horizontal-to-vertical ratio for a projected area projected from the projection lens. <EOS>
