Abstract: A lens array includes a flat plate-shaped base part, a plurality of lenses, a plurality of columnar light guiding parts and a plurality of light shielding parts. The lenses are formed on one surface of the base part. The columnar light guiding parts are formed on another surface of the base part at points corresponding to the lenses. The light shielding parts are formed at least on lateral surfaces of the light guiding parts.

Abstract: An optical writing device includes: a light emitting substrate on which light emitting device groups obtained by grouping light emitting devices is arranged; a lens array including image forming lenses condensing light emitted from the light emitting devices on an image carrier; a first base material including the lens array; and a second base material including the light emitting substrate or the lens array, wherein the first and/or second base materials, each of which includes a joint formed in a joint part with the other member, is a transparent body, the joint includes a metal layer, an intermediate layer providing a peak of total transmissivity of the joint in a first wavelength band, and a marker for alignment, the first and second base materials are joined via the metal layer, and the light emitting devices emit light of a wavelength band out of the first wavelength band.
