PURPOSE: To prevent the generation of disturbance in array, etc., of optical fiber ribbons by constituting the optical fiber cable in such a manner that the charges electrified by static electricity in the optical fiber ribbons and a spacer flow out through conductive attaching materials to the outside even if the optical fiber ribbons of the spacer is electrified.

CONSTITUTION: The conductive attaching materials 21 consisting of aluminum tapes, etc., are previously disposed in the ribbon housing grooves 3 of the spacer 1 in the case plural sheets of the optical fiber ribbons 4 are superposed on each other and are housed into these ribbon housing grooves 3. The conductive attaching materials 21 may be in a tape form to be previously wound in the ribbon housing grooves 3 or may be a fine wire form to be wound together with the optical fiber ribbons 4 into the ribbon housing grooves 3. The attaching materials of the fine wire form are removable afterward.
