Water stop structure for wire harness and wire harness

A water stop structure for a wire harness comprising:

• a cylindrical shield shell which is disposed at an intermediate portion of a shield member in a longitudinal direction, the shield member covering one or plural conducting paths, and which is made of an electrically conductive metal;
• an outer water stop mechanism which is disposed on a side of an outer peripheral surface of the cylindrical shield shell;
• and
• an inner water stop mechanism which is disposed on a side of an inner peripheral surface of the cylindrical shield shell,
• wherein the inner water stop mechanism has an elastic water stop plug member;
• and
• wherein a shell-side seal portion which is in watertight contact with the inner peripheral surface of the cylindrical shield shell and one or plural conducting path-side seal portions which are in watertight contact with outer peripheral surfaces of covers of the conducting paths are formed on the water stop plug member, the one or plural conducting path-side seal portions being formed so as to pass through the water stop plug member.
