LENS ARRAY UNIT, IMAGING DEVICE, METHOD FOR MANUFACTURING LENS ARRAY UNIT, AND METHOD FOR MANUFACTURING IMAGING DEVICE

摘要

Provided is a thin lens array unit such that overlapping between adjacent single-element images can be prevented, and such that warping and reduction in strength can be prevented while simplicity in production is ensured. A flare stop layer (25) having openings (25b) corresponding to second lens elements (23e) is provided on the image-side surface of a transparent substrate (21) which is part of a second lens array (20) nearest to the image side, and thus the flare stop layer (25), which can be easily manufactured, can limit the range of light emitted from the lens array unit (100). Particularly, each of the plurality of openings (25b) covered by a second lens element (23e) has a rectangular or an elongated contour, thus allowing overlapping of single-element images due to adjacent second lens elements (23e) to be prevented and allowing the array density of the second lens elements (23e) or imaging elements (51) to be increased.
