A method for fabricating an optical element having excellent heat resistance and exhibiting excellent adhesion to a substrate. The optical element is fabricated by sticking a liquid composition for forming an optical element to the forming surface of a basic material having a patterned surface, arranged regularly with high wettability areas and low wettability areas, as the forming surface and then forming protrusions in the high wettability areas by hardening the composition. The composition for forming an optical element contains at least one kind of compound selected from a condensable hydrolytic compound or a hydrolytic condensate thereof.

L'invention concerne un procédé de fabrication d'un élément optique, présentant une excellente résistance thermique et une excellente propriété d'adhésion sur un substrat. Ce procédé de fabrication consiste à faire adhérer une composition liquide, servant à former un élément optique, sur la surface de formage d'un matériau de base présentant une surface modelée, sur laquelle des zones de mouillabilité élevée et des zones de faible mouillabilité sont agencées de manière régulière. Ce procédé consiste ensuite à former des saillies dans les zones de mouillabilité élevée en faisant durcir ladite composition. Cette composition, qui sert à former un élément optique, renferme au moins un type de composé sélectionné parmi un composé hydrolytique condensable et un condensé hydrolytique dudit composé.
