PROBLEM TO BE SOLVED: To provide an optical fiber cable of which transmission characteristic is not deteriorated even under a severe environment, and which has durability against a temperature variation, and an excellent waterproof effect, and the coating of which can easily be removed. SOLUTION: In the optical fiber, a coated optical fiber is coated by a sheath layer which is composed of a polyamid type thermoplastic resin. In the coated optical fiber, two coating layers made of an ultraviolet setting type resin are formed around the outer periphery of a quartz type glass fiber, the outer coating layer contains urethan (metha) acrylate oligomer, and 1 to 20 pts.wt. silicone type acrylate in the coating resin of 100 pts.wt., and further contains at least one of alkyl type ester compound, alkenyl type ester compound and trimellitic ester compound of 1 to 40 of pts.wt.
