An automotive lamp comprising: a first lamp unit that has a first projection lens ; a second lamp unit that has a second projection lens ; and an inter-lens region illumination lens that is arranged such that the inter-lens region illumination lens covers a region between the first projection lens and the second projection lens when viewed from the front of the lamp and such that the inter-lens region illumination lens radiates, toward the front of the lamp , light that is emitted from at least one of the first projection lens and the second projection lens and that enters the inter-lens region illumination lens , wherein, when viewed from the front of the lamp , the inter-lens region illumination lens covers the first projection lens and the second projection lens and has a shape that is the same as or similar to a shape formed by the first projection lens and the second projection lens that are connected to each other, characterized in that the vertical length (Lv1) of the first projection lens is longer than the vertical length (Lv2) of the second projection lens when viewed from the front of the lamp , and wherein the horizontal length (Lh2) of the second projection lens is longer than the horizontal length (Lh1) of the first projection lens when viewed from the front of the lamp , wherein the first lamp unit forms a first pattern (Pa, Pa1, Pa2, Pa3) that constitutes a portion of a low beam light distribution pattern (Lo), and wherein the second lamp unit forms a second pattern (Pb, Pb1, Pb2, Pb3) that constitutes the other portion of the low beam light distribution pattern (Lo) and that has a shape more diffused in a substantially horizontal direction than the first pattern (Pa, Pa1, Pa2, Pa3). a first lamp unit that has a first projection lens ; a second lamp unit that has a second projection lens ; and an inter-lens region illumination lens that is arranged such that the inter-lens region illumination lens covers a region between the first projection lens and the second projection lens when viewed from the front of the lamp and such that the inter-lens region illumination lens radiates, toward the front of the lamp , light that is emitted from at least one of the first projection lens and the second projection lens and that enters the inter-lens region illumination lens , wherein, when viewed from the front of the lamp , the inter-lens region illumination lens covers the first projection lens and the second projection lens and has a shape that is the same as or similar to a shape formed by the first projection lens and the second projection lens that are connected to each other, characterized in that the vertical length (Lv1) of the first projection lens is longer than the vertical length (Lv2) of the second projection lens when viewed from the front of the lamp , and wherein the horizontal length (Lh2) of the second projection lens is longer than the horizontal length (Lh1) of the first projection lens when viewed from the front of the lamp , wherein the first lamp unit forms a first pattern (Pa, Pa1, Pa2, Pa3) that constitutes a portion of a low beam light distribution pattern (Lo), and wherein the second lamp unit forms a second pattern (Pb, Pb1, Pb2, Pb3) that constitutes the other portion of the low beam light distribution pattern (Lo) and that has a shape more diffused in a substantially horizontal direction than the first pattern (Pa, Pa1, Pa2, Pa3). <EOS>
