PURPOSE:To improve lens performance and to reduce manufacturing cost by constituting a waveguide lens of the cumulative monomolecular film of a photopolymerizable olefin compd. so that sharp-edged microshapes are easily formed. CONSTITUTION:A cumulative monomolecular film 10 (hereunder abbreviated as LB film) is formed on a substrate 2 by a Langmuir-Blodgett's method (hereunder abbreviated as LB method) using a photopolymerizable monomer (e.g.; formula I , formula II) having a hudrophilic group, hydrophobic group and at least one unsatd. bond in the molecule. After the LB film 10 is patterned and exposed, the unexposed part is dissolved away by developing the film to build a lower part 11 of a waveguide consisting of the polymerized LB film. The polymerizable LB film 12 is formed by the LB method on a part 11 and the film 12 is exposed to a grating pattern by an energy ray 7 and is developed to dissove away the unexposed part, by which the intended waveguide lens is obtd. |
