PROBLEM TO BE SOLVED: To provide a multifilament yarn and woven and knitted fabric in which spinning operability or the like is favorable, and cool sensitivity, an ultraviolet-prevention property and a sheer-prevention property when being wet are excellent.SOLUTION: A multifilament yarn includes: a synthetic resin part in which a percentage content X (mass%) of an inorganic oxide fine particle is 2<X≤10; and a synthetic resin part in which a percentage content Y (mass%) of the inorganic oxide fine particle is 2 mass% or less, and the multifilament yarn whose cross-sectional shape satisfies the following (1)-(4). (1) The synthetic resin part in which the percentage content X (mass %) of the inorganic oxide fine particle is 2<X≤10 is a multi-leaf shape that includes 6-20 leaf parts radially directing from a center side of single yarn to an outer peripheral side. (2) A tip of an outer peripheral side of the leaf part has a curve shape. (3) The synthetic resin part in which the percentage content X (mass%) of the inorganic oxide fine particle is 2<X≤10 is that a ratio of an exposure length (μm) to the single yarn surface is 10% or less. (4) An average ratio of the shortest distance (μm) from a circumference of the single yarn to the leaf part is 10% or less.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である合成樹脂部と無機酸化物微粒子の含有率Ｙ（質量％）が２質量％以下である合成樹脂部を含むマルチフィラメント糸であって、横断面形状が（１）〜（４）を満足するマルチフィラメント糸。（１）無機酸化物微粒子の含有率Ｘ（質量％）が２＜Ｘ≦１０である合成樹脂部が単糸の中心側から外周側へ放射状に向かう６〜２０個の葉部を含む多葉形状。（２）葉部の外周側の先端部が曲線形状。（３）無機酸化物微粒子の含有率Ｘ（質量％）が２＜Ｘ≦１０である合成樹脂部の前記単糸表面への露出長（μｍ）割合が１０％以下。（４）単糸の外周から葉部までの最短距離（μｍ）の平均比率が１０％以下。【選択図】図１
