A wire harness comprising:

• an electric wire having conductivity;
• and
• a connector provided at an end of the electric wire, wherein
• the connector includes:
• a casing including a cylindrical section that holds, on an inside, a terminal provided at the end of the electric wire and is fitted with a mating connector of a connection target in a fitting direction;
• a packing that seals an annular space between an outer peripheral surface of the cylindrical section and the mating connector;
• a fastening member that is attached to penetrate the inside of the cylindrical section in the fitting direction from a through-hole formed in one end face in the fitting direction of the casing, and is fixed to a fixed wall surface of the connection target in a state in which the cylindrical section and the mating connector are fitted with each other;
• and
• a seal member that seals an annular gap between an outer peripheral surface of the fastening member and an inner surface of the through-hole, wherein
• the fastening member includes:
• a bolt inserted through the through-hole;
• and
• a first waterproof washer including a first annular washer main body interposed between a head of the bolt and a peripheral edge portion of the through-hole, and a first annular water cutoff rubber interposed between an inner surface of the first annular washer main body and a shaft section of the bolt, and
• the seal member is interposed between the outer peripheral surface of the shaft section of the bolt and the inner surface of the through-hole, and is positioned adjacent to the first annular water cutoff rubber in the fitting direction.
