The duct unit includes a duct in which a sound guiding space is formed, a duct holder on which the duct is mounted, and a duct cover that covers a part of the duct. A shared space is formed between the duct holder and the duct cover, the space having a discharge port that is communicated with the sound guiding space and is capable of discharging moisture. The duct is provided with a restriction wall portion that separates at least a part of the shared space into a first path that enable passage of moisture and a second path that is communicated with the sound guiding space.
