Branching structure and wire harness

A wire harness comprising:

• a main line harness to be arranged on a body of a vehicle, the main line harness comprising a plurality of main lines arranged side by side, each of the main lines being configured as a wiring member having a rod conductor, and one of the main lines being a power supply line having a predetermined current capacity;
• a branch line harness to be connected to electrical components mounted on the vehicle, the branch line harness comprising a plurality of branch lines;
• and
• a control box arranged to distribute electric power fed to the power supply line of the main line harness to the branch line harness to be connected to the main line harness,
• wherein the control box comprises a branching structure configured to connect the main line harness and the branch line harness to each other,
• wherein the branching structure comprises connection terminals to be electrically connected to the main lines to form at least part of electrically conductive paths between the main lines and the branch lines, and
• wherein each of the connection terminals comprises a tubular connection portion having a tubular shape to cover an outer circumferential surface of the rod conductor, the tubular connection portion comprising a pressing structure configured to elastically press the outer circumferential surface of the rod conductor placed inside a hollow portion of the tubular connection portion.
