The transmissivity of the polarized light p does not decrease and the reflectivity of the polarized light s is nearly 100% with respect to even a broad angle region.

    Abstract: A rising mirror is constructed by forming on a glass substrate a first region and a second region having different reflection properties. The first region is formed of, for example, an antireflection film, and the second regions is formed by superimposing a phase adjustment layer for adjusting the phase of reflected light and a dielectric multilayer film in this order. Forming the phase adjustment layer on the glass substrate in this manner permits, for example, phase adjustment such as eliminates phase shift in reflected light between the regions, and phase adjustment such as cancels out phase shift caused by the objective lens of the optical disc, thereby permitting suppressing disturbance in the wave front of reflected light as whole.
