PROBLEM TO BE SOLVED: To provide an electric connection box which enables improvement of waterproofness achieved by an exterior member, and to provide a wire harness and the exterior member.SOLUTION: A corrugate tube T includes: a sandwiched part t10 sandwiched by an exterior installation part 37 and a corrugate cover 4; and a small diameter part t20 having an outer diameter smaller than an outer diameter of the sandwiched part t10. The structure reduces a gap between electric wires W exposed from the small diameter part t20 and the small diameter part t20 without exchanging the exterior installation part 37 with the corrugate cover 4 and prevents water from entering into an electric connection box from the gap between the electric wires W exposed from the small diameter part t20 and the small diameter part t20 when the corrugate tube T is applied to the electric wires W having a relatively small diameter.SELECTED DRAWING: Figure 2
【課題】外装部材による防水性を高めることができる電気接続箱、ワイヤハーネス、及び、外装部材を提供する。【解決手段】コルゲートチューブTは、外装設置部37とコルゲートカバー4とにより挟持される被挟持部t10と、外径が被挟持部t10の外径よりも小さい小径部t20とを備える。これにより、比較的小径の電線WにコルゲートチューブTを適用する場合に、外装設置部37とコルゲートカバー4とを交換することなく、小径部t20から露出する電線Wと小径部t20との隙間を削減し、小径部t20から露出する電線Wと小径部t20との隙間から水が浸入することを防ぐ。【選択図】図2
