Abstract
A light source includes a substrate on which an excitation light source is mounted, a lens including a light transmitting portion that transmits light from the excitation light source and a body attached to the substrate, a first thermal expansion absorber that protrudes from the body and has high heat resistance and elasticity, and a cover fixed to the substrate in a state where the body of the lens is sandwiched between the cover and the substrate via the first thermal expansion absorber.
