  • the cable connecting structure 3C according to the third embodiment as shown in FIGS FIGs. 9A and 9B shown.
  • the cable connection structure 3C includes the round cables W1 each having a round cross section and having the core wire 1a and the round insulating jacket 1b covering the outer periphery of the core wire 1a, the flat cable W2 having a cross section in a flat rectangular shape Shape and the tabular conductor 2a and the conductor 2a covering flat insulating sheath 2b, wherein the holder 10A holds the end portions of the round cable W1 and the end portion of the flat cable W2 and pulls the round cable W1 and the flat cable W2 in the same direction in an overlapping state , the connecting portions 20 in which the core wires 1a connected from the end portions of the round cables W1 and the conductors 2a exposed from the end portion of the flat cable W2 held by the holder 10A are connected, and the heat-shrinkable tube 24 to which the hot-melt adhesive 23 is attached is, as a waterproof outer section, d it together covers the outer periphery of the holder 10A and the outer circumference
  • the round cables W1 and the flat cable W2 are pulled out of the holder 10 in the same direction, whereby they are connected to a connecting device such as the ultrasonic welding device 30 regardless of a length of the Flat cable W2 can be manufactured.
  • the holder 10 is divided into the round cable holder 11 and the flat cable holder 15. However, it can be a component.
  • the holder 10A is a component.
  • the holder 10A may be made of two components as in the cable connection structure 3A according to the first embodiment and the cable connection structure 3B according to the second embodiment.
  • the tube-shrinking step is performed so that the flat cable W2 is bent to be guided and adjusted in a direction other than the extended direction from the holder 10A.
  • the flat cable W2 may not be bent, and the tube shrinking step (heating with respect to the shrink tube 24 and hot melt adhesive 23) may be performed while the flat cable W2 and the round cables W1 are pulled out of the holder 10A in the same direction.
  • the shrink tube 24 which changes shape by thermal action is used.
  • it may be a shrink tube that changes its shape by exposure to light or the like.
  • the core wires 1a of the round cables W1 and the conductors 2a of the flat cable W2 are ultrasonically welded to the ultrasonic welding apparatus 30.
  • a terminal device capable of electrically connecting the core wires 1a of the round cables W1 and the conductors 2a of the flat cable W2 which may be, for example, a resistance welding device.
