PROBLEM TO BE SOLVED: To efficiently manufacture a lens array composed of a plurality of lenses with high accuracy. SOLUTION: After an adhesive 6 is applied on the surfaces of a plurality of lens arrays 1, 2 having a plurality of optical curved faces, the plurality of lens arrays 1, 2 are positioned with respect to each other so that the optical axes of the optical curved faces corresponding to each other are aligned. Then the lens arrays 1, 2 are joined by hardening the adhesive 6 while the plurality of lens arrays 1, 2 are pressurized. |
