A vehicular lamp including, within a lamp chamber s defined by a lamp body 10
and an outer cover 20, an led 28 which is the light source, and a
light guide 24 which guides light emitted from the led 28 by internal
reflection so as to emit light at a plurality of locations. the light guide 24
is constructed of a coupling unit u1 that extends along the outer cover
20 and is made of a plurality of light guiding members 25, the surface
of each light guiding member 25 formed in an elliptical surface 25a
that has a pair of focal points f, are coupled in series while sharing the
focal points with each other at coupling portions 26, and the focal points
f at both end portions of the light guide 24 (coupling unit u1) are
near the light-emitting portion 29 of the led 28.
