An antibacterial member is constituted such that a propolis component is contained in, or adhered to, a water-insoluble base member. This antibacterial member is mixed into a filter member to be disposed in a flow passage in an antibacterial filter. Water in the antibacterial filter receives the antibacterial action from the propolis component when coming in contact with the antibacterial member. Thus, microorganisms in water is extinguished, and generation and propagation of germs, bacteria, algae and the like are suppressed.
