Abstract: Disclosed is a reverse osmosis membrane filter for increasing a recovery rate of purified water by extending a residence time of raw water on a reverse osmosis sheet. The reverse osmosis membrane filter having a fluid channel formed on a side surface thereof, according to the present invention, comprises: a central tube having a purified water inflow hole radially formed therein; a guide tube that is coupled to the outside of the central tube and has a raw water moving passage formed in the longitudinal direction thereof and a raw water outflow hole radially formed therein which communicates with the raw water moving passage; a reverse osmosis membrane sheet that filters a foreign substance contained in raw water and supplies the filtered purified water into the central tube through the purified water inflow hole; and a filter housing that accommodates the reverse osmosis membrane sheet.
