PROBLEM TO BE SOLVED: To provide a light diffusion material capable of coating glass surface of a window expected to have a high PR advertisement effect without spoiling a view or a glass surface of a head-up display and capable of being peeled off from a glass surface without giving any damage to the window glass, and to provide a light diffusion member using the same and a light diffusion structure.SOLUTION: The light diffusion material is a resin having the transmission ratio of full visible light is 70% or more in which cerium oxide fine particles are dispersed. Average particle diameter of the cerium oxide particles is preferably in a range of 10 to 400 nm. The light diffusion member includes a transparent base material which is coated with the light diffusion material. The light diffusion structure has the light diffusion member.SELECTED DRAWING: None 【課題】 宣伝広告効果が期待される窓のガラス面やヘッドアップディスプレイ用のガラス面等にコートした際に、眺望を犠牲にすることなく、また、コート剤を剥がす際に、窓ガラスを傷つけることのない光拡散材、それを用いた光拡散部材及び光拡散構造物を提供する。【解決手段】 酸化セリウム微粒子を分散した全可視光透過率が７０％以上の樹脂からなる光拡散材。酸化セリウム粒子の平均粒子径が１０〜４００ｎｍの範囲であると好ましい。前記の光拡散材を透明基材にコーティングした光拡散部材。この光拡散部材を有する光拡散構造物。【選択図】 なし
