An oil-water separation apparatus is provided which can easily separate and collect oil from a liquid mixture containing water and oil at low cost. The oil-water separation apparatus includes an oil-water-separating member configured to separate a liquid mixture containing water and oil into moisture and oil, and a liquid reservoir subdivided into an upper region and a lower region by the oil-water-separating member. The oil-water separation apparatus filters the liquid mixture by gravity. The oil-water-separating member includes a base which includes a channel for the liquid mixture. The oil-water-separating member is formed in the base, and the oil-water-separating member contains a fluorine compound which has an oil-repellency-imparting group and a hydrophilicity-imparting group. A drain port for discharging the moisture is formed in the lower region of the liquid reservoir.
