PROBLEM TO BE SOLVED: To produce a lens array excellent in optical characteristics with good production efficiency at a low cost. SOLUTION: The objective method for producing a lens array has a step for molding a lens array body including plural lenses 11 having convex lens faces 11a, 11b and a holder part 10 which holds the lenses 11 in an integrated state from a translucent resin and a shading treatment step for forming a shading film 3 on at least one face 10a, 10b of the holder part 10 connected with the lens faces 11a, 11b. The shading treatment step includes a step for applying a coating material to the holder part 10 while enclosing the lens faces 11a, 11b and a step for solidifying the applied coating material after melting by heating. |
