PURPOSE:To improve adhesiveness, durability and optical characteristics by using silicon dioxide to constitute the 1st, 3rd and 5th layers, which are formed by vapor deposition successively from a surface side to an air side on the surface of optical parts made of plastic, and using cerium oxide to constitute the 2nd layer and 4th layer. CONSTITUTION:The 1st layer 2 consisting of the silicon dioxide, the 2nd layer 3 consisting of the cerium oxide, the 3rd layer 4 consisting of the silicon dioxide, the 4th layer 5 consisting of the cerium oxide, and the 5th layer 6 consisting of the silicon dioxide are successively deposited by evaporation on the surface of the optical parts 1 made of plastic from the surface side to the air side. The antireflection film having the excellent adhesiveness to the optical parts made of plastic, durability and optical characteristics is formed in such a manner. |
