Abstract
The refractive index of the inner core part 11 in a region in contact with the boundary of the outer core part 12 is higher than the refractive index of the outer core part 12. The refractive index of the outer core part 12 is gradually decreased from the inner circumferential side to the outer circumferential side. The refractive index of the inner cladding part 21 is equal to the refractive index of the outermost circumferential part of the outer core part 12 and not greater than the refractive index of the outer cladding part 22.
