PROBLEM TO BE SOLVED: To provide an inner surface antireflection coating material and a method for manufacturing an optical element, in which reflectance by inner surface reflection can be easily decreased even when the coating material is layered on an antireflection coating layer.SOLUTION: An inner surface antireflection coating material Pis used for a lens 1 that is manufactured by forming an antireflection coating layer 5. An inner surface antireflection layer 3 of the lens 1 is formed by using the inner surface antireflection coating material Pwhich includes a fluorocarbon resin or low refractive index nanoparticles comprising magnesium fluoride or hollow silica, and a coloring material. |
