PROBLEM TO BE SOLVED: To provide a vehicular oxygen enrichment device capable of efficiently supplying oxygen-enriched air of high oxygen concentration to an occupant by selectively separating the intended oxygen from nitrogen to realize recovery from fatigue of an occupant, and prevent sleepiness and car sickness, and to form a comfortable ride environment. SOLUTION: The vehicular oxygen enrichment device comprises a solid electrolyte type oxygen pump to selectively separate at least only oxygen in air from nitrogen, an air supply passage on the primary side of the solid electrolyte type oxygen pump, and an oxygen supply passage on the secondary side of the solid electrolyte type oxygen pump, and the oxygen separated by the solid electrolyte type oxygen pump is supplied into a cabin from an oxygen supply outlet formed in the oxygen supply passage.
