PROBLEM TO BE SOLVED: To provide a hologram recording material which achieves a high refractive index change, flexibility, high sensitivity, low scattering, environment resistance, durability, a low dimensional change and high multiplicity, and is suitable for volume hologram recording, and to provide a hologram recording medium. SOLUTION: The hologram recording material contains an organometallic compound having an organometallic unit essentially comprising at least two metals, oxygen and aromatic groups, wherein two aromatic groups bond directly to one metal, and a photopolymerizable compound. One of the at least two metals is Si and the other metal is preferably selected from the group consisting of Ti, Zr, Ge, Sn, Al and Zn. The organometallic unit is preferably one in which two aromatic groups bond directly to one Si. The hologram recording medium 11 has a hologram recording material layer 21.
