A cell multiplexing apparatus includes a transmitting section in which information fields of a plurality of ATM cells intended for transmission along the same path are multiplexed and stored into an information field of one multiplexed cell. A representative VPI, globally representing the VPIs of the plurality of ATM cells intended for transmission along the same path, is assigned as the VPI of the multiplexed cell for transmission. A receiving section detects the representative VPI from received cells and the plurality of ATM cells having individual VPIs and transmitted along the same path are reconstructed from the multiplexed cell having the representative VPI. The VPI area of the ATM header of the multiplexed cell is divided into two segments. The representative VPI designating the path for the multiplexed cell is carried in one segment and VPI information of the plurality of ATM cells intended for transmission along the same path is carried in the other segment.
