ABSTRACT:
A reflecting optical element is disclosed which includes the following articles.The reflecting optical element is constituted by:a base member having a continuous curved-surface portion, anda resin layer integrally formed of resin on the curved surface of the base member, and having a plurality of mutually discontinuous curved surfaces to be reflecting surfaces. The base member is made of a material smaller in coefficient of linear expansion than the resin for forming the resin layer.Thus, a reflecting optical element is provided which is low in optical-performance deterioration caused by the temperature effect, and small in the number of restraints in fabrication.
