PROBLEM TO BE SOLVED: To provide a vehicular oxygen-enriched air feeder capable of suppressing sense of incongruity of an occupant caused by dew condensation. SOLUTION: A vacuum pump 120 evacuates an oxygen enricher 110 through a duct 130. In the oxygen enricher 110, outside air passing through a suction port of a casing 100 is sucked toward the vacuum pump 120 through an oxygen enrichment membrane. Oxygen out of outside air is preferentially introduced to generate oxygen-enriched air. The oxygen-enriched air is fed into a cabin through the duct 130, the vacuum pump 120 and a cylindrical part 151 of a water discharge unit 150. Even if condensate occurs, it flows outside the vehicle from the cylindrical part 151 through a water discharge duct 152, suppressing the flow of condensate generated by oxygen-enriched air into the cabin.
