PROBLEM TO BE SOLVED: To provide a wavelength characteristic variable composite metal nano particle for forming the increasing/sensitizing field of photo-reaction causing reaction at a three-dimensional arbitrary position in a substance, also to provide a multiphoton absorbing reaction material of high sensitivity using it and a multiphoton absorbing reaction aid, and to enable the adaptation of the composite metal nano particle to an ultra-high density and super-precise product. SOLUTION: The composite metal nano particle, which is prepared by coating the surface of a core particle (e.g., a gold nano rod) having shape anisotropy with a metal film (e.g., silver) for developing a plasmon increase field, and the multiphoton absorbing material (e.g., diaryl ethene, an acrylate or epoxy type photosetting resin, etc.) are mixed to be adapted to a three-dimensional optical recording medium, a three-dimensional shaping material, a fluorescent microscope, etc. COPYRIGHT: (C)2008,JPO&INPIT
