    摘要: An optical resin material, which, while able to form a plastic optical element produceable at low cost, has excellent heat resistance and, at the same time, has excellent optical stability high enough to avoid a change in optical properties even after use for a long period of time, and an optical element using the optical resin material. The optical resin material contains a curable resin and hydrophobic oxide particles and is characterized in that it satisfies an absorbance intensity ratio B/A of not less than 0.01 and not more than 0.25, wherein A represents an absorbance intensity at 1720 cm−1 in an infrared absorption spectrum of the optical resin material after curing; and B represents an absorbance intensity at 1637 cm−1, and the volume average particle diameter of the hydrophobic oxide particles is not less than 1.0 nm and not more than 50 nm.
