An optical fiber cable produced at low cost is provided, in which an optical fiber core covered with an outer covering is suppressed from moving inside the outer covering in the lengthwise direction thereof and which does not cause the transmission characteristics to be deteriorated even when the cable is bent. In the optical fiber cable, buffer members composed of a long fiber are longitudinally disposed or stranded around at least one optical fiber core, the buffer members and the optical fiber core are adhered together intermittently in the lengthwise direction, and an outer covering is provided to surround the buffer members.
