To provide a vehicular illuminating device excellent in design and to provide a vehicular illuminating device that can be manufactured at a low cost.SOLUTION: A illuminating device 13 provided in a roof lining 10 of a motorcar 1 comprises: a light guide plate 40 formed of a light transmissive plate-like member and having light-emitting portions 41L, 41R that emit predetermined-pattern light from a plate surface 40A inside a vehicle compartment and a plate surface 40B outside the vehicle compartment; and a reflecting plate 30 disposed on a vehicle compartment outside of the light guide plate 40 so as to be superposed on the light guide plate 40. The reflecting plate 30 comprises, on a plate surface inside the vehicle compartment, an uneven portion 31 formed from projections 32L, 32R, projecting toward the light guide plate 40 and recesses 33L, 33M, 33R, receding away from the light guide plate 40. By means of the uneven portion 31, the predetermined-pattern light emitted outside the vehicle compartment from the light guide plate 40 by the light-emitting portions 41L, 41R is reflected inside the vehicle compartment while refracting.SELECTED DRAWING: Figure 3
