Abstract

To provide a reverse osmosis membrane module capable of suppressing clogging thereof by microorganisms, and to provide a water purification system capable of being used always. The reverse osmosis membrane module 1 is provided with a reverse osmosis membrane 11 formed in a bag shape, a permeated-water-side spacer 12 disposed on the inner face of the reverse osmosis membrane 11, and a supplied-water-side spacer 13 disposed on the outer face of the reverse osmosis membrane 11. An antibacterial and antifungal agent is blended in the supplied-water-side spacer 13 of the reverse osmosis membrane module 1. When a faucet 7 is closed, the antibacterial and antifungal agent blended in the supplied-water-side spacer 13 is eluted into water remaining in the set place of the supplied-water-side spacer 13.
