Lamp unit and vehicle lamp

A lamp unit, comprising:

• an installation base unit provided with a plurality of light sources;
• a converging lens that converges light from the plurality of light sources;
• a light blocking member provided with a plurality of slit units that allows partial passage of the light that has been converged by the converging lens;
• and a projection lens that projects the light that has passed through the light blocking member, to form an illumination pattern having a plurality of illumination figures corresponding to the plurality of slit units, the installation base unit, the converging lens, the light blocking member, and the projection lens being arranged along a lamp unit axis, wherein
• the projection lens has a reference focal point set on the lamp unit axis,
• the projection lens and the light blocking member are rotated downward about the reference focal point, and
• the installation base unit and the converging lens are rotated downward about an installation base unit reference point set behind and above the reference focal point.
