Abstract

See full text

An optical component includes a base material and a film containing silica particles and conductive transparent metal oxide particles. The conductive transparent metal oxide particles are preferably composed of SnO2. The number-based average particle diameter of the conductive transparent metal oxide particles is preferably 0.8 nm or more and 5.0 nm or less. When the content of the silica particles in the film is represented by Xs (vol %) and the content of the conductive transparent metal oxide particles in the film is represented by Xc (vol %), it is preferred to satisfy the following relationship: 0.003≦Xc/Xs≦0.12.
