A method for placing fluorescent single molecules on a surface of a substrate includes dropping a sample solution in which fluorescent molecules are dissolved in a predetermined concentration in a volatile, organic solvent, onto a slip of paper placed on the substrate and pulling the slip of paper so as to make the dropped sample solution traverse the surface of the substrate before the organic solvent evaporates. Since a single molecular layer of fluorescent molecules with high uniformity can be placed readily on the surface of the substrate, measurement of fluorescence and measurement of scattered light can be carried out accurately and structural defects of the surface of substrate can be visualized from luminous spots of fluorescence and from luminous spots of scattered light.
