Abstract:
Disclosed is a vehicle lamp including: a light source; and a projection lens that projects light emitted from the light source. The projection lens is constituted by a triplet lens including a first lens having a positive refractive power, a second lens having a negative refractive power, and a third lens having a positive refractive power, and a first inter-lens distance (t1) between the first lens and the second lens, a second inter-lens distance (t2) between the second lens and the third lens, and a total lens thickness (T) of the projection lens are in a relationship that satisfies 0.03
