Abstract: An aspect of the invention provides an illumination structure that can illuminate both a neighborhood of an opening and a storage portion with a simple configuration. An illumination structure 1 includes an illumination device 4 provided in an opening 3 of a vehicle 2, and a person can get on and off the vehicle 2 through the opening 3. The illumination device 4 is fixed to a step garnish 5 provided in a lower end portion 3a of the opening 3. A translucent member 18 is provided in a bottom surface of a storage portion 9 formed in a door lining 10. When a door 6 is closed against the opening 3, the storage portion 9 is disposed on the step garnish 5, whereby the illumination structure 1 is retained while the illumination device 4, a first translucent member 18a, and a second translucent member 18b line up in the order from the bottom.
