The inner surfaces of the heat-shrinkable sleeves are closely layered between these branch cables by providing space between them, and the branch cables pulled out from the heat-shrinkable sleeves are kept close to each other. This allows the branch cable to be placed in a dense layer on the inner surface of the heat-shrinkable sleeve, and the inner surface of the heat-shrinkable sleeve and the outer jacket of the heat-shrinkable sleeve to be heat-sealed in a dense layer. This has the effect of improving the sealing performance of the cable branch connection.
