There is provided an antibacterial fiber, an antibacterial twisted yarn and an antibacterial cloth which exhibits high durability to post-processing with water, detergent, staining or the like at a small added amount. In an antibacterial fiber200, an antibacterial property imparting glass composition10 is fixed in a form of, for example, a particle on the surface of a fiber substrate16 and/or dispersed and complexed in the fiber substrate16. An antibacterial property imparting glass composition 10 comprises 0.1 to 5.0% by weight of Ag2O in a composition containing 45-67 mol% of P2O5, 5 to 20 mol% of A12O3, 1 to 40 mol% of 1 or 2 or more selected from MgO, CaO and ZnO, and 20 mol% or less of B2O3. An antibacterial fiber200 containing such the antibacterial property imparting glass composition10 at a ratio of, for example, 0.1 to 5.0% by weight shows high water resistance, acid resistance, alkali resistance and detergent resistance in antibacterial property.
