A lighting film which includes a base member having optical transparency, a plurality of protrusions having optical transparency, which are formed to be adjacent to each other on one surface of the base member, and a gap portion formed between the protrusions, in which an area of an end surface of the protrusion on a base member side is greater than an area of an end surface of the protrusion on a side opposite to the base member, and a ratio s/w of an interval s of two adjacent protrusions among the plurality of protrusions to a width w of the protrusion is equal to or less than 0.1.
