An optical fiber is a linear radiator uniform in the longer direction thereof, and a lighting device uses the optical fiber. The optical fiber is a lighting fiber having a core and a cladding. In the fiber, as the cladding, there is used a polymer obtained by polymerizing a polymerizing ingredient containing 90% or more by weight of vinylidene fluoride, and the cladding has a crystallinity of 45% to 52%.
