Joint structure between end of coaxial cable and terminal, and joining method therebetween

A joining method between an end of a coaxial cable and a terminal for joining an end of an outer conductor of the coaxial cable in which the outer conductor including a plurality of outer core wires is coaxially and integrally formed with and around an inner conductor via an insulation inner coat with the terminal and an outer periphery of the outer core wires is covered with an insulation outer coat, the joining method comprising the steps of:

• removing the insulation outer coat of end portion of the coaxial cable;
• bending a joint end of the plurality of ends of outer core wires in a direction crossing a longitudinal direction of the cable;
• and
• ultrasonically joining the joint end with a joint surface in a state where the joint end is radially brought into contact with the joint surface of a conductor connection portion of the terminal disposed in a direction crossing an axial direction of the cable.
