PROBLEM TO BE SOLVED: To provide an method for inexpensively manufacturing an optical fiber array with half-pitch in which curvature of primary coated optical fiber arrays is small. SOLUTION: The method includes: a first step for arraying a plurality of primary coated optical fibers 4 to an optical fiber arraying fixture 3; a second step for tentatively fixing the coated optical fibers to a tentative fixing substrate by contacting the side of a tentative fixing resin material of the tentative fixing substrate to which a tentative fixing resin material 2 is applied to the arrayed primary coated optical fibers; a third step for fixing the tentatively primary coated fixed optical fibers to an optical fiber fixing substrate 5 via a fixing resin material 6, a fourth step for separating the tentative fixing substrate from the primary coated optical fibers together with the tentative fixing resin material; and a fifth step for fixing a cover board to the side where the tentative fixing substrate of the primary coated optical fibers is separated via a reinforcing resin material 7. The method is characterized in that when the fixing resin material 6 in the third step is cured, the region 10 in contact with the primary coated optical fiber 4 arrays is hardened with priority and then, the region 9 situated outside the arraying direction of the primary coated optical fibers 4 is cured.
