PROBLEM TO BE SOLVED: To provide a travel route presentation device for presenting a travel route capable of reducing influences of air pollutants discharged from a vehicle to its environment. SOLUTION: The travel route presentation device includes: a candidate travel-route extraction part 151 for extracting a plurality of candidate travel routes which can arrive at an input destination by referring to a map database stored in a storage device 119; an air-pollutant absorption calculation part 152 for referring to an air-purifying-object database indicative of presence places of air purifying objects having ability to absorb air pollutants discharged from vehicles for each candidate travel route extracted by the extraction part 151, and calculating amounts of air purifying objects present within a predetermined distance determined according to the displacement of the vehicle at the periphery of the candidate travel route; and an eco-route selection part 153 for selecting and outputting a travel route used for the travel guidance of the vehicle from among the plurality of candidate travel routes based on the amounts of the air purifying objects calculated by the calculation part 152.
