摘要：
A holographic recording medium which has parallelism of high precision and causes little substrate deformation ascribable to contraction of its recording areas when recording interference fringes, and a method for manufacturing the same. The holographic recording medium has a holographic recording material layer between a first transparent substrate and a second transparent substrate. This holographic recording material layer is formed integrally with a spacer which is composed of a large number of spherical beads arranged so as to surround recording areas for interference fringes to be recorded on.
