An object of the invention is to provide an antibacterial liquid with excellent temporal stability in which caking due to sedimentation of solid components does not occur and with which a film capable of stably maintaining antibacterial properties can be formed, in a case of being formed into a film. Another object is to provide an antibacterial film formed using the antibacterial liquid. Still another object is to provide a spray and a cloth including the antibacterial liquid.;The antibacterial liquid of the invention includes an antibacterial microparticle, a binder, and a solvent, in which the antibacterial microparticle contains a silver-supporting inorganic oxide, the binder includes at least one compound having a siloxane bond, the solvent includes an alcohol and water, the concentration of solid contents is less than 5% by mass with respect to the total mass of the antibacterial liquid, and the content of the compound having a siloxane bond is 60% by mass or more with respect to the total solid content
