According to one embodiment, an interference exposure apparatus of the embodiment includes a light path changing section in which a changing element adapted to change a light path direction and a light path length of a plurality of light beams with respect to the plurality of light beams having coherency with respect to each other is arranged substantially axisymmetrically; and an adjusting section for adjusting one part of the light beam entering a substrate by intensity changing or phase changing one part of the light beam corresponding to a pattern shape to form on the substrate. A light beam exit from the light path changing section and the adjusting section is interfered on the substrate to carry out an interference exposure on the substrate. |
