This light irradiation device is provided with a light-emitting structure 4 and a case structure 1 for housing the light-emitting structure 4. A shock-absorbing structure 65 is provided between the light-emitting structure 4 and the case structure 1 in order to cushion and absorb propagation, to the light-emitting structure 4, of external impact acting on the case structure 1.
