A headlight reduced in size and ensuring sufficiently high efficiency is provided. The headlight includes a light source (1), a cylindrical condenser lens (2) surrounding the light source from its periphery to transmit light incident from the light source, and a reflector (3) surrounding the light source and the cylindrical condenser lens from their backsides to reflect the light transmitted through the cylindrical condenser lens frontward. <IMAGE> |
