An optical element which exhibits a great improvement in durability even after repeated use. The optical element comprising a substrate having thereon (a) a recording layer comprising a liquid crystal polymer composition and (b) a surface protective layer in this order, in which the protective layer comprises a plurality of layers laminated such that the hardness thereof increases from the layer adjacent to the recording layer toward the uppermost layer in order, or the protective layer comprises a plurality of layers laminated such that the glass transition point thereof becomes higher from the layer adjacent to the recording layer toward the uppermost layer in order. Furthermore, the layer adjacent to the recording layer preferably has a pencil hardness of HB or higher and the uppermost layer preferably has a pencil hardness of 3 H or higher.
