The present disclosure provides a waterproof unit and a wire harness capable of suppressing a decrease in waterproofness. The waterproof unit (31) has: a tubular waterproof member (50) fitted to a through-hole (200X) of a vehicle body panel (200) provided between the outside of the vehicle interior, which is a waterproof region, and the inside of the vehicle interior, which is a non-waterproof region; and a tubular waterproof member (90) provided in the vehicle interior so as to be separated from the waterproof member (50). The waterproof unit (31) is provided with a corrugated pipe (100) which is arranged between the waterproof member (50) and the waterproof member (90) and is connected with the waterproof member (50) and the waterproof member (90). The flexural rigidity of the bellows (100) is higher than the flexural rigidity of the waterproof member (50).
