Summary:PROBLEM TO BE SOLVED: To provide an imaging lens capable of finely adjusting the optical axis of the lenses included in the imaging lens and shifting and adjusting the optical axis without using any dedicated tools. SOLUTION: The imaging lens 100 includes a mechanism that shifts and adjusts the optical axis of adjustment lenses 114b to 114e. The imaging lens 100 has an adjustment lens frame 126 for supporting the adjustment lenses 114b to 114e. The adjustment lens frame 126 includes a lens holding part 130 deformable perpendicular to the optical axis 102 of the imaging lens 100. An adjusting member 140 for deforming the lens holding part 130 is fixed to the adjustment lens frame 126 while keeping the lens holding part 130 deformed. COPYRIGHT: (C)2008,JPO&INPIT
