The purpose of the present invention is to improve the performance of a device for manufacturing a composite stranded wire, and to reduce the size of the device. The composite stranded wire is provided with a first stranded wire formed by twisting a plurality of wire rods and a second stranded wire formed by twisting a plurality of wire rods (7a) around the first stranded wire. The manufacturing device of the composite stranded wire is provided with a cylindrical rotating cage (1) for guiding the plurality of wire rods; a plurality of wire feeding spools (7) which are arranged in the inner space of the cylindrical rotating cage in the direction of the axis of rotation of the cylindrical rotating cage and which supply wires, respectively; a stranding port (4) for stranding the plurality of wire rods around the first stranded wire; a stranded wire feeding spool (8) which is disposed between the cylindrical rotating cage (1) and the stranding port and supplies a first stranded wire; and a bow-shaped path wire (2
