PROBLEM TO BE SOLVED: To provide a multi-core cable capable of aligning central conductors at intervals smaller than the outer diameter of the internal insulator and reducing the connection width. SOLUTION: The multi-core cable 10 includes a plurality of parallel coaxial cables 20 each of which contains a central conductor 21, an internal insulator 22 placed outside the central conductor 21, an external conductor 26 placed outside the internal insulator 22, and an outer sheath 27 placed outside the external conductor 26. The internal insulator 22 of the coaxial cable 20 includes a cylindrical part 22a covering the periphery of the central conductor 21 and a plurality of wall plates 22b radially extending from the cylindrical part 22a outwards in the radial direction. Groove-like spaces 25 are formed between the wall plates 22b. The exposed internal insulators 22 are in contact with each other and aligned in a plane to form an alignment section 11b. Adjoining internal insulators 22 are within a circle which is concentric to the periphery of the coaxial cable 20 while passing by the front ends of the plurality of wall plates 22b in the radial cross-section of the internal insulators 22 in the alignment section 11b.
