A ventilation member is configured to be attached to an opening portion of a housing, and includes: an inner member configured to be fitted to the opening portion and including a tubular portion having a through hole configured to serve as a part of a ventilation path between a space inside the housing and a space outside the housing; and an outer member mounted to the inner member and covering a water-proof gas-permeable membrane attached so as to close an opening of the through hole. The inner member and the outer member have an exposed surface subjected to liquid-repellent treatment.
