Abstract

An optical element of a lens mirror array according to an embodiment includes an incident-side lens surface, a first reflection surface, a second reflection surface, an emission-side lens surface, a first positioning surface, and a second positioning surface. The incident-side lens surface refracts and converges incident light. The first reflection surface reflects light made incident via the incident-side lens surface. The second reflection surface reflects the light reflected by the first reflection surface. The emission-side lens surface emits the light reflected by the second reflection surface. The lens mirror array is a lens mirror array in which a plurality of optical elements are arrayed in a direction orthogonal to optical axes of the incident light and the reflected light and parallel to the first positioning surface.
