There is provided an erect equal-magnification lens array including: a plurality of first lenses causing light incident from an object point to each incidence plane, which has at least a partially planar shape, to be collected by each outgoing plane which has a convex shape; a plurality of second lenses aligned so as to correspond to each of the plurality of first lenses, having incidence planes each of which has a convex shape and is arranged in the vicinity of a position in the optical axis direction, at which the light is collected by each of the outgoing planes of the plurality of first lenses, and causing the light incident to each of the incidence planes to be collected again on an image plane using outgoing planes thereof each of which has a convex shape; and an aperture configured to shield light, from among the light collected by each of the outgoing planes of the plurality of first lenses, proceeding in a direction to be incident from each of the outgoing planes to the incidence planes of the second lenses other than the second lenses on the same optical axis.
