摘要： The present invention relates to a pipe made of synthetic resin having a plurality of internal tubes, wherein silicone coating layers are formed on the respective inner circumferential surfaces of the plurality of internal tubes which are accommodated in an external tube, such that long optical fibres or electrical wires or the like inserted in the same can be readily and easily accommodated while water repellency is maintained, and failure to fuse or deformation of any of the side surfaces of the internal tubes, which are fused to the inner circumferential surface of the external tube, can be prevented when the internal tubes are formed integrally on the external tube, and the plurality of internal tubes can be stably inserted into and joined by fusing onto the inner circumferential surface of the external tube, and deformation due to temperature differences between the external tube and the internal tubes during cooling can be prevented while the internal tubes are inserted into and joined by fusing onto the inner circumferential surface of the external tube in a hermetic state.
