To provide a hollow fiber membrane bundle that provides a hollow fiber membrane module concurrently achieving low dusting characteristics and high durability, the hollow fiber membrane module comprising the same, and a cartridge.SOLUTION: A hollow fiber membrane bundle comprises a plurality of polyketone hollow fiber membranes each having a one-side end and the other-side end, and an adhesive that provides a fixed end surface by fixing the one-side ends of the plurality of polyketone hollow fiber membranes, the other-side ends of them or both of them to one another under the condition of holding hollow part openings of the polyketone hollow fiber membranes. The residual amount of a solvent in the polyketone hollow fiber membrane is 200 ppm or less.SELECTED DRAWING: Figure 1 【課題】低発塵性及び高耐久性が同時に実現される中空糸膜モジュールを与える中空糸膜束、並びにこれを備える中空糸膜モジュール及びカートリッジを提供する。【解決手段】一端と他端とを有する複数のポリケトン中空糸膜と、前記複数のポリケトン中空糸膜の前記一端、前記他端又はこれらの両者を、前記ポリケトン中空糸膜の中空部開口を保持したままで互いに固定して固定端面を与える接着剤とを有する、中空糸膜束であって、前記ポリケトン中空糸膜中の溶媒残存量が２００ｐｐｍ以下である、中空糸膜束。【選択図】図１
