A hollow fiber package body for separation of fluid comprising a core and layers of hollow fibers having a selective permeability arranged around said core, said hollow fiber, layers being formed by tape-like bundles of hollow fibers said bundles composed of an arrangement of hollow fibers in nearly parallel relations to one another and in a flat state, said bundles having been turned back near the end of said package body while being held by at least one string or band, the width of each hollow fiber bundle being from 15 to 50,000 d (where d is the outer diameter of a hollow fiber) and the ratio of the thickness to the width of each hollow fiber bundle being from 1/20,000 to 1/5, said hollow fiber bundles being arranged in multi-layers by intersecting at least at one spot between one end and the other end of said package body, and said hollow fiber bundles being arranged in mutually and up- and downwardly intersecting relationships crossing two or more adjacent layers. A membrane separation device comprising a tubular container having an entrance for fluid and a hollow fiber package body according to claim 1 accommodated in said container.
