Abstract
A lens arrayis formed as an erect 1:1 imaging lens by superimposing two lens platesandtogether. Each lens plateconsists of a number of micro lenseswhich are regularly provided at a predetermined pitch and in a two-dimensional manner. This lens plateis for example made by press molding the ultraviolet curing resin in a soft condition using a transparent mold and by irradiating the ultraviolet light on the ultraviolet curing resin from outside for hardening. Since the lens arrayis provided with micro lensesin rows in a sub-scanning direction, deterioration of an amount of light level resulting from the displacement between a light axis of the lens and an image sensoris not generated.
