The bottom surface has distances between opposite sides of the bottom surface and has a longest distance among the distances. The at least one light emitting element is disposed on the bottom surface of the recess portion and has a polygonal shape which has five or more sides and which has a longest diagonal line viewed along the front direction. Each internal angle of the polygonal shape is less than 180°. The longest diagonal line of the polygonal shape is parallel to a lateral line along the longest distance.
