A method for manufacturing optical fibers with filter, wherein a multilayer-film filter is formed at end face of the optical fibers, comprising a process for fixing each of the optical fibers on a fixing jig, a process for polishing the end face of the optical fiber fixed on said fixing jig, a process for film-forming a filter on the end face of the optical fibers after polishing, and a process for taking out said optical fibers from said fixing jigs, respectively, wherein said process for film-forming the filter is performed by forming a fiber bundle in which a plural number of optical fibers after polishing, on which the filter has been film-formed, are tied such that all polished planes are aligned at the end face.
