PROBLEM TO BE SOLVED: To provide a two-photon absorption thin film that significantly increases sensitization of two-photon absorption characteristics, and to provide a method of manufacturing the same. SOLUTION: The method includes: a step of immersing a substrate [10] the surface of which is charged in an aqueous coating solution containing organic polymer ions (a) having charges with polarity opposite to that of the substrate and metal nanoparticles, and drying it to obtain a thin film [11]; a step of immersing the substrate in the aqueous coating solution containing the organic polymer ions (b) having charges with polarity opposite to that of (a) and two-photon absorption materials, and being drying it to obtain a thin film [12]; or, a step of immersing the substrate the surface of which is charged in the aqueous coating solution containing the organic polymer ions (b) having charges with polarity opposite to that of the substrate and two-photon absorption materials, and drying it to obtain the thin film [12]; and a step of immersing the substrate in the aqueous coating solution containing the organic polymer ions (a) having charges with polarity reverse to that of the (b) and metal nanoparticles, and drying it to obtain a thin film [11]. Thereby, the two-photon absorption thin film is obtained which includes an interlamination thin film of the thin film [11] and the thin film [12] on the substrate [10].
