Abstract
Provided are a lamp unit that can form an irradiation pattern on a road surface almost without tilting an inclination of a lamp unit axis with respect to the road surface, and a vehicle lighting tool using the lamp unit. A lamp unit includes: a light source; a condenser lens that condenses light from the light source; a light-shielding member (shade) provided with an irradiation slit through which the light condensed by the condensing lens partially passes; and a projection lens that projects the light that passes through the light-shielding member (shade) to form an irradiation pattern, which are arranged along a lamp unit axis. The projection lens has a reference focus set on the lamp unit axis, and is disposed at such a position rotated downward about the reference focus, and a projection lens axis is directed further downward than the lamp unit axis.
