Abstract

The present invention is provided with low-beam light source units (1, 2), a high-beam light source unit (3), and a projection lens (4) for projecting light from each of the light source units (1, 2, 3) to form a desired light distribution. A projection lens (4) is integrally formed with: low-beam lens sections (41, 42) that project light from low-beam light source units (1, 2) and form low-beam light distribution; and a high-beam lens unit (43) that projects light from the high-beam light source unit (3) and forms high-beam light distribution. Further, the high-beam light source unit (3) is provided with a correction optical unit (32) that suppresses lens aberration.
