PROBLEM TO BE SOLVED: To obtain a method for manufacturing an optical member capable of reducing manufacturing cost of the optical member, and a method for manufacturing an exposure device.SOLUTION: When a lens array 56 is manufactured, lens members 154 are disposed between a pair of side plate members 114 by stacking the lens members 154 between the pair of side plate members 114. Therefore, manufacturing cost is reduced compared with a case where the lens members are disposed by horizontally arranging the lens members. |
