PROBLEM TO BE SOLVED: To provide a false-twisted hollow multifilament yarn and a woven or knitted fabric good in spinning operability or the like, excellent in sensation of coolness, ultraviolet-blocking properties and anti-transparency when it is wet.SOLUTION: There is provided a false-twisted hollow multifilament yarn containing a first resin part 2 having a content X (mass%) of an inorganic oxide fine particle of 2<X≤10 and a second resin part 3 having a content Y (mass%) of the inorganic oxide fine particle Y of 2 mass% or less. The false-twisted hollow multifilament yarn comprises single fibers 1, in which a ratio of a single fiber whose hollow percentage is 3% or more is 2 single fibers or more per 100 single fibers 1. A synthetic resin constituting the first resin part 2 and the second resin part is a polyester resin, and a mass ratio of the first resin part 2 to the second resin part 3 is 30/70 to 90/10. The false-twisted hollow multifilament yarn has a crimp percent of 5 to 25%.SELECTED DRAWING: Figure 1 【課題】紡糸操業性等が良好であり、涼感性、紫外線防止性及び湿潤時の透け防止性に優れる仮撚中空マルチフィラメント糸及び織編物の提供。【解決手段】無機酸化物微粒子の含有率Ｘ（質量％）が２＜Ｘ≦１０である第一の樹脂部２と、無機酸化物微粒子の含有率Ｙ（質量％）が２質量％以下である第二の樹脂部３を含む仮撚中空５マルチフィラメント糸であって、中空５率が３％以上である単糸１が１００本の単糸１あたり２本以上含まれる仮撚中空５マルチフィラメント糸。第一の樹脂部２及び第二の樹脂部を構成する合成樹脂がポリエステル樹脂であり、第一の樹脂部２と第二の樹脂部３との質量比（第一の樹脂部／第二の樹脂部）が３０／７０〜９０／１０であり、前記仮撚中空マルチフィラメント糸の捲縮率が５〜２５％である仮撚中空マルチフィラメント糸。【選択図】図１
