Claim:
1. A film-containing base plate (II) for use in fabricating a lens array including a lens array main unit (I) including: a first surface and a second surface spaced from each other in an optical axis direction (hereinafter referred to as a z-direction); a plurality of lens surfaces formed and aligned on the first surface along a predetermined alignment direction which is perpendicular to the z-direction (hereinafter referred to as a x-direction); a planar optical plane on the second surface, through which light that has passed the plurality of lens surfaces is to pass, the planar optical plane defining a predetermined central area of the second surface, which predetermined central area encompasses an entire orthographic projection area formed on the second surface when projecting the lens surfaces from the z-direction toward the second surface, a surrounding area being defined on the second surface around the predetermined central area, the planar optical plane being defined by a bottom surface of a recess that is concave relative to the surrounding area and depressed toward the lens surfaces, the planar optical plane extending in a direction perpendicular to the z-direction; and a pair of first guide holes or guide pins that are disposed on opposite sides in relation to the planar optical plane in the x-direction on the surrounding area of the second surface, the pair of first guide holes or guide pins extending parallel to the z-direction, an adhesion area (i) being defined, which contains part of the orthographic projection area projected from at least part of the plurality of lens surfaces, on the planar optical plane of the lens array main unit (I), said film-containing base plate (II) comprising:
