Abstract
A lens array element has a rectangular plate-like external shape, and includes plate surfaces that functions as light transmission surfaces; and a plurality of cellular lenses that are formed on at least one of the plate surfaces. Each of end facesof the rectangular plate-like external shape forms an inclined surface that slants inward from a plate surfaceon one side toward a plate surfaceon the other side, and a reference surfaceperpendicular to the plate surface is formed on a part of at least two adjoining end faces among the end faces. A front view shape of the reference surface region arranged side-by-side with the inclined surface of the end face is a trapezoid, an oblique sideof the trapezoid is disposed so as to extend from a plate surface on one side toward the plate surfaceon the other side, and an upper sideof the trapezoid is disposed on a side of the other of the plate surfaces. Regarding the reference surface provided to the rectangular plate-like end face for optical alignment, the occurrence of inaccuracy due to the releasing properties at the time of molding the lends array element using a metal mold is suppressed.
