PROBLEM TO BE SOLVED: To provide a water absorptive optical fiber satisfying a reduced optical fiber cable diameter, low contraction and high strength by particularly providing a completely dry loose tube optical fiber cable while improving the waterproof of the loose tube or the optical fiber cable. SOLUTION: A water absorptive optical fiber 1 includes: a single core optical fiber 3; a water soluble UV resin 5 substantially uniformly disposed on the outer periphery of the single core optical fiber 3; and a powdered absorbent 7 substantially uniformly fixed in/on the water soluble UV resin 5 by use of the water soluble UV resin 5 as a binder.
