A water-repellent woven or knitted fabric which contains a mixed entangled yarn and has a water-repellent agent adhered onto the surface thereof. The mixed entangled yarn is configured from a polyester fiber A having a single fiber fineness of 0.2 to 0.9 dtex and a total fineness of 30 to 100 dtex and a polyester fiber B having a single fiber fineness of 1.0 to 5.0 dtex and a total fineness of 30 to 100 dtex. The single fiber fineness ratio (A/B) of the polyester fiber A to the polyester fiber B is in the range from 1/20 to 1/5. The mass ratio (A/B) of the polyester fiber A to the polyester fiber B is in the range from 20/80 to 80/20. On the surface portion of the mixed entangled yarn, protrusions of the polyester fiber A are formed. The rate of elongation (a fixed loading method, load: 14.7 N) of the fabric as measured in accordance with JIS L 1096:2010 is 3% or less in the case where the fabric has a woven form and is 120% or less in the case where the fabric has a knitted form.
