To provide a flame retardant bundle spun yarn having high anti-pilling property, and a flame retardant woven fabric and a flame retardant protective clothing including the same.SOLUTION: A flame retardant bundle spun yarn 1 is mainly composed of aramid fibers. Inner fibers 2 of the flame retardant bundle spun yarn 1 are aligned in a yarn length direction in a state of being scarcely twisted relatively in comparison with surface layer winding fibers 3. The flame retardant bundle spun yarn 1 has no intermittent binding point. The surface layer winding fibers 3 bundle the inner fibers 2 in a real twisted state of being twisted in one direction. The inner fibers 2 and the surface layer fibers 3 have a structure in which fibers are entangled from the surface toward the inside by migration and include the aramid fibers, anti-static fibers, and other fibers. The other fibers are at least one fiber selected from polyester, wool, rayon, cotton, vinylon, acryl, polyetherimide, blended yarn of them, and these flame retardant fibers.SELECTED DRAWING: Figure 1 【課題】抗ピル性が高い難燃性結束紡績糸とこれを含む難燃性織物及び難燃性防護衣類を提供する。【解決手段】アラミド繊維を主成分とする難燃性結束紡績糸１であり、難燃性結束紡績糸１の内部繊維２は表層の巻き付き繊維３に比較して相対的に撚りが少ない状態で糸長方向に配列しており、難燃性結束紡績糸１には間欠的な結束点はなく、表層の巻き付き繊維３は一方向に撚りが掛けられた実撚り状で内部繊維２を束ねており、内部繊維２と表層繊維３はマイグレーションにより、繊維が表面から内部に入り組んでいる構造であり、アラミド繊維と帯電防止繊維と他の繊維を含み、他の繊維は、ポリエステル、ウール、レーヨン、コットン、ビニロン、アクリル、ポリエーテルイミド、これらの混紡品、及びこれらの難燃繊維から選ばれる少なくとも一つの繊維である。【選択図】図１
