PROBLEM TO BE SOLVED: To align a multiplicity of fibers 1, 1, etc., in a longitudinal direction and transverse direction, respectively, with good accuracy by making the offset of the fibers 1, 1, etc., from their array direction as small as possible when a multifiber bundle Bu is manufactured by aligning the terminal parts of a multiplicity of the fibers 1, 1, etc., in such a manner that these terminal parts line up respectively straight in both of the longitudinal direction and transverse direction. SOLUTION: Fiber sheets 13 are formed by inserting the fibers 1, 1, etc., of the number of pieces corresponding to the transverse direction of the multifiber bundle Bu respectively into V-grooves 5, 5, etc., of a V-groove jig 4 to line up the fibers to one row, pressing the respective fibers 1 in a pressurized state in such a manner that the outer peripheries of the respective fibers 1 come into contact at two points with groove flanks 5a and 5a of the V-grooves 5, 5, etc., of the V-groove jig 4 and bonding and integrating a multiplicity of the fibers 1, 1, etc., pressed and held at the V-groove jig 4 by adhesives 11. Such fiber sheets 13 of the number corresponding to the number in the longitudinal direction of the multifiber bundle Bu are laminated and pressurized to multiple stages in the state of putting the sheets between fitting groove parts 16 and 16 of a pair of sheet aligning jigs 15 and 15 and multiple stages of the laminated fiber sheets 13 are bonded and integrated.
