The disclosure improves the light emission state while refining the design appeal of the housing. The first emitting surface (71a) comprises a first spherical surface (71b) protruding in a direction of light emission, and second spherical surfaces (71c, 71d) disposed radially outward of the first spherical surface (71b) and configured to emit light to an exterior so as to approach a direction of the light emitted from a center of the first spherical surface (71b) to an exterior. The light emitted to an exterior from the second spherical surfaces (71c, 71d) is brought closer to a direction of the light emitted from the first spherical surface (71b), so that even in the winker lamp (10) designed in an elongated rod shape, interference between light emitted from the first emitting surface (71a) and light emitted from the second emitting surface (62d) is suppressed.

The disclosure provides a vehicle lighting fixture (10) capable of obtaining stipulated photometric property without increasing size. A substrate (50) mounting a linear array of first to fourth light sources (D1~D4), and a lens (40) having an opposing surface (41a) facing the first to fourth light sources (D1~D4), are provided, wherein the opposing surface (41a) has first to fourth Fresnel lens parts (61~64) facing respectively the first to fourth light sources (D1~D4), and a straight lens part (70) provided to extend across the first to fourth Fresnel lens parts (61~64), and the straight lens part (70) is disposed on both sides of a base line (BL), with the base line (BL) passing through centers of the first to fourth Fresnel lens parts (61~64) as a center.
