An optical fiber manufacturing method comprises preparing first base materials each of which includes at least one core forming part to form a core and a cladding forming part to form a cladding; performing a first elongating to form second base materials by forming a first bundle by bundling two or more base materials including at least one of the first base materials having been prepared at the preparing and by thermally elongating the first bundle; and performing a second elongating at least once to form a second bundle by bundling two or more base materials including at least one of the second base materials and by thermally elongating the second bundle, wherein the second bundle is thermally elongated up until the point when the optical fiber is formed at the second elongating.
