An optical cable connecting section in an electric power and optical composite cable which has a rodlike excessive length containing member having linear grooves and curved grooves on the outer periphery thereof and disposed between the ends of both of the optical cables to be connected, further connected in series with the tension members of the optical cables in such a manner that the optical fibers led from the end of both of the optical cables are relatively connected as pairs, whereby the excessive length portions of the optical cables thus connected are contained in the curved grooves of the excessive length containing member and the portions having no excessive length are contained in the linear grooves of the excessive length containing member. Thus, the connecting sections of the optical cables can improve in the outer diameter of the connecting sections of the optical cables so as to increase as large as the occurrence of a defect in its handling to be uniformly finished in the outer diameter of the cable over the entire length.
