Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an org. nonlinear optical material which does not require an electric field orientation treatment for SHG(second harmonic generation) development, is small in orientation relaxation and exhibits excellent stability as a THG(ternary harmonic generation) element by using DNA(deoxyribonucleic acid) as a base material into which org. dyestuff molecules are introduced. SOLUTION: A lipid is added to an aq. soln. of DNA to deposit a DNA-lipid compd. insoluble in water (S11). The soln. is subjected to filtering, washing and dialyzing (S12), then to freeze drying (S13) to obtain the DNA-lipid compd. from which impurities are removed. The DNA-lipid compd. is dissolved in an org. solvent (S14) and the soln. is cast to form a transparent film (S15). The resulted transparent film is immersed into a soln. of the org. dyestuff molecule having nonlinear optical characteristics and the org. dyestuff molecule are inserted into the DNA-lipid compd. within the transparent film (S16). Further, the film is stretched (S17), by which the optical film is obtd.
