PROBLEM TO BE SOLVED: To provide a printed circuit board capable of suppressing occurrence of a shadow by a cable connected to a connector arranged in a connector arrangement part.SOLUTION: A printed circuit board 21 includes a body part 22, a plurality of light source arrangement parts 32 and connector arrangement parts 42. The body part 22 extends in the longitudinal direction D. The plurality of light source arrangement parts 32 are arrayed to the body part 22. The connector arrangement parts 42 are arranged to the body part 22. The body part has a light source region S regulated by the arrayed plurality of light source arrangement parts 32. The light source region S is regulated by an inside boundary line s1, an outside boundary line s2 longer than the inside boundary line s1, and side part boundary lines s3, s4 for connecting the inside boundary line s1 and the outside boundary s2. The connector arrangement parts 42 are arranged further outside than the outside boundary line s2, and in the vicinity of end parts in the longitudinal direction D.SELECTED DRAWING: Figure 4 |
