<P>PROBLEM TO BE SOLVED: To provide an observation device for observing a sample state in an observation plane vicinity, that is improved in absorption spectrum detecting sensitivity, by totally reflecting light on an observation plane of a first component, arranging a plurality of metallic particles spaced apart on a surface of a second component separated from the observation plane by a level equal to or less than a wavelength, and measuring a light absorption spectrum arising from an electromagnetic field reinforced by plasmon resonance induced by the totally reflected light and the metallic particles. <P>SOLUTION: An observation device having a structure in which a separating space between a plurality of metallic particles spaced apart is filled with the same material as a material of a second component on the surface of which the metallic particles are formed. For example, the space between the metallic particles is filled with particles made of the material of the second component. <P>COPYRIGHT: (C)2013,JPO&INPIT |
