Abstract: In a manufacturing apparatus for flat cable adapted for allowing plural conductive wires arranged on the same plane to be put between a first insulating tape on which first peeling sheets are stuck at predetermined intervals and a second insulating tape on which second peeling sheets are stuck at predetermined intervals to stick the first insulating tape, the conductive wires and the second insulating tape in order recited, such an approach is employed to respectively adjust tensions applied to the first and second insulating tapes to thereby respectively independently change expansions/contractions of the first and second insulating tapes. Thus, it is possible to correct sticking errors of the first peeling sheets and the second peeling sheets.
