Claim 14:
15. A lens body bonding method using at least a first lens body of a plurality of lenses arranged linearly in a longitudinal direction and a second lens body of a plurality of lenses arranged linearly in the longitudinal direction and in which the first lens body and the second lens body are bonded to each other to align linearly along the longitudinal direction, the lens body bonding method comprising:
a lens body fixing step of fixing the first lens body and the second lens body to, using an adhesive layer, a surface of a lens fixing plate determined by intersection of a straight line in an optical axis direction of the first lens body and the second lens body and a straight line in the longitudinal direction, such that the lens fixing plate in which a lens fixing plate opening is formed in the lateral direction intersecting the optical axis direction and the longitudinal direction overlaps, when viewed in the lateral direction, at least a portion of a junction at which the first lens body and the second lens body are bonded to each other;
a lens body adjustment step of adjusting positions of the first lens body and the second lens body by
bringing a first adjuster into contact with the first lens body via at least one hole into which the first adjuster is inserted, the at least one hole included in holes formed in the lens fixing plate in the lateral direction so as to sandwich, when viewed in the lateral direction, the junction such that at least one of the holes is provided for each of the first lens body and the second lens body,
bringing a second adjuster into contact with the second lens body via at least one hole that is included in the holes and into which the second adjuster is inserted, and
moving at least one of the first adjuster adjustment member or the second adjuster forward or backward along the lateral direction; and

a resin portion forming step of injecting resin through the lens fixing plate opening and filling with the resin a space between (i) the first lens body and the second lens body and (ii) the lens fixing plate opening.
