- the connecting portion of the coaxial wire harness 16 is arranged such that a plurality of (for example, seven) coaxial cables 10 are arranged so as to contact each other, and then the outer cover 14 is formed on both surfaces of a part of the length of the seven coaxial cables 10 in the longitudinal direction.
- the sheet 20 made of the same material as the re-melting material is disposed, and then the heat source 30 is applied from both sides of the sheet 20 to weld the sheet 20 and the outer jacket 14 together.
- the same material as that of the first embodiment can be adopted as the material of the jacket 14 and the insulator 12.
- each coaxial cable 10 is integrated by coupling

- the bundle unit 22 can be bundled from the middle.
- a linear coaxial harness can be formed.
- the sheet 20 may be welded to only one surface of each coaxial cable 10, or the sheet and the coaxial cable may be welded by directly applying the heat source 30 to the sheet 20, and indirectly from the heat source 30 to the sheet and the coaxial cable. Alternatively, heat may be applied to weld them.
- the same effect as that of the first embodiment can be obtained. Furthermore, in the first embodiment, if the jacket 14 is thin, the area of the portion where each coaxial cable 10 is welded is reduced. However, in the second embodiment, the sheet 20 is melted and the recesses between the lines are formed in the cross-sectional view of FIG. Since the area of the melted portion is increased by filling, the adhesion of each wire is further increased, and the durability against a strong impact such as twisting is further improved.
- the structure of the coaxial wire harness of the second embodiment is flat like FPC, and various shapes of wiring materials can be created.
- the center conductor 11 is AWG46 (diameter 0.0984 mm)
- the thickness including the sheets 20 on both sides can be set to 0.3 mm.
- this structure has better noise characteristics than FPC. Flexibility can also be improved by making the bundle part 22 into the part bent at the time of wiring.
- the coupling portion is only a part in the length direction such as the coupling portions 10a, 10b, 10c, 10d or the coupling portions 20a, 20b, 20c, 20d. It can also be all parts.

Twenty coaxial cables 10 are arranged without a gap, sandwiched from both sides by a sheet 20 (ETFE tape) having a width of 2 mm and a thickness of 0.05 mm, and hot pressed at 260 ° C. (about the melting point of ETFE) The ETFE jacket 14 of the coaxial cable 10 and the ETFE sheet 20 were welded and integrated to form a coaxial harness. This coaxial harness does not change or peel off even if it is immersed in a thermostatic bath at 85 ° C for 96 hours or exposed to high temperature and high humidity (65 ° C, 95% RH) for 96 hours. it can.
