Vehicle lamp

A vehicle lamp including a light source and a light guide body configured to guide light emitted from the light source toward a side in front of the vehicle lamp,

• wherein the light guide body includes a first light guide portion having a semicircular shape centered on a light-emitting portion of the light source and a second light guide portion arranged at a position farther away from the light-emitting portion than the first light guide portion,
• wherein the first light guide portion has a first light-input-side side surface that is positioned away from the light-emitting portion and that is based on an arc centered on the light-emitting portion on which diffused light emitted from the light-emitting portion enters, and a first light-output-side side surface that is positioned on an opposite side of the first light-input-side side surface and that is based on an arc concentric with the arc of the first light-input-side side surface, the first light-output-side side surface including a first light output surface from which light entered from the first light-input-side side surface and being guided inside the first light guide portion is output,
• wherein the second light guide portion has a second light-input-side side surface that is facing the first light-output-side side surface and that is based on an arc concentric with the arc of the first light-input-side side surface, a second light-output-side side surface that is formed on an opposite side of the second light-input-side side surface and that is substantially parallel to the first light-output-side side surface, and a plurality of light guide paths that project in a direction farther away from the light-emitting portion than the second light-output-side side surface and that have light-emitting portions in a distal end region,
• wherein the plurality of light guide paths are aligned and arranged so that their light-emitting portions are spaced apart in a first direction,
• wherein a second light input surface for inputting light output from the first light output surface to the second light guide portion is formed on the second light-input-side side surface corresponding to a proximal-end portion of each of the plurality of light guide paths,
• wherein a first light output portion serving as a refractive surface for condensing light from the light source input from the first light-input-side side surface toward the second light input surface after being guided inside the first light guide portion as substantially parallel light rays is provided on the first light output surface corresponding to each of second light input surfaces, and
• wherein each second light input surface becomes a substantially flat surface orthogonal to the substantially parallel light rays output from the first light output portion.
