摘要
Optical fiber accommodating grooves (14) are formed at the outer circumferential portion of an optical fiber accommodating portion body (12) of a slotted rod (10) for an optical fiber cable. At least portions, where the optical fiber accommodating grooves (14) are formed, of the optical fiber accommodating portion body (12) are constructed of a foaming body, whereby flexibility of the slotted rod (10) is prevented from worsening. A solid layer having a smooth surface is formed on at least the inner circumferential surface, which is brought into contact with optical fibers, of the above optical fiber accommodating grooves (14). The optical fibers are accommodated in the optical fiber accommodating grooves (14) to provide the slotted rod (19) with a shielding layer at the outside, thereby forming an optical fiber cable, wherein the optical fibers accommodated in the optical fiber accommodating grooves (14) are prevented from being bent by the walls of the grooves, and optical loss of the optical fibers can be prevented from being increased.
