Abstract:
[Problem] To provide a multicore parallel cable having a small transmission loss, and a method for manufacturing the same. [Solution] The problem is solved by a multicore parallel cable 10 comprising a plurality of coaxial cables 3 disposed in parallel in one direction, and a film-like outer conductor 4 provided on an outer periphery of the plurality of coaxial cables 3. The film-like outer conductor 4 includes a recessed portion 7 between the coaxial cables 3, 3 disposed in parallel, at least a part of the recessed portion 7 being disposed along the outer periphery of the coaxial cables 3. Preferably, L/D is in a range of 0.01 to 0.45, where L is the amount of depression of the recessed portion 7 and D is the outer diameter of the coaxial cables 3. Further, the film-like outer conductor 4 is wound longitudinally along the plurality of coaxial cables 3, and the recessed portion 7 is preferably formed in an overlap portion 8 of the film-like outer conductor 4.
