PROBLEM TO BE SOLVED: To provide an optical cable manufacturing method in which a protective body and a jacket are molded using the same crosshead, in which molding with a thermoplastic resin can be performed in one process, and in which adhesiveness between the jacket and the protective body can be increased. SOLUTION: In the optical cable manufacturing method, a tension body 3 is arranged on both sides of a coated optical fiber 2 and then, a protective body 4 composed of a thermoplastic resin is arranged across the coated optical fiber 2 on both sides where no tension bodies 3 are arranged, with the entirety integrally covered with a jacket 6. To the crosshead for performing extrusion molding of the jacket 6, the thermoplastic resin material for molding the protective body 4 is supplied, molding the prescribed shape and making the protective body 4 covered integrally together with the coated optical fiber 2 and the tension bodies 3 by means of the crosshead.
