To make a tape length that can be supplied at one time long, and to make it possible to directly supply a tape from a record wound tape. A tape supplying method of this invention includes: connecting a tape end to an outer side of one record wound tape of a first record wound tape and a second record wound tape and a tape end to an inner side of another record wound tape, by matching a surface and a rear surface of the tapes; and after the connecting, supplying a tape of the first record wound tape and the second record wound tape from a tape end of the first record wound tape to an opposite side of a side that has been connected to the second record wound tape.

An optical fiber cable includes an elongated optical element portion having an optical fiber, a pair of tensile strength members and an outer jacket. The optical fiber is composed of one or more plastic coated optical fibers, tight-buffered optical fibers or optical ribbon fibers. The pair of tensile strength members is arranged in parallel at both sides of the optical fiber in a width direction of the optical fiber. The outer jacket covers outer circumferences of the optical fiber and the pair of tensile strength members. A frictional coefficient of the outer jacket is equal to or less than 0.20. Shore D hardness of the outer jacket is equal to or more than 60.
