PROBLEM TO BE SOLVED: To solve problems that a light flux utilization rate is low and inefficient in a conventional vehicular headlight, because irradiation directions cannot be controlled for the light within the range where a reflecting mirror is unable to catch the light from the light source, especially because no controlling method is available for the light in the direction of the lens. SOLUTION: By this headlight in which the light source is almost covered by a plurality of oval reflecting face parts of which the light source is a first focus, and light emitting ports are formed in the position of the second focus of respective oval reflecting faces, and by installing parabolic reflecting face parts of which the light emitting ports are the focus points, the utilization efficiency on the light emitted from the light source is enhanced, so that realization of the vehicular headlight which is 1.5 to 2 times brighter is possible even if the light source is the same.
