The method of manufacturing a microstructure having metal microbodies which generate an enhanced electric field includes forming, in a substrate, micropores each of which opens out on a surface of the substrate, has an inside diameter that varies in a depth direction, and has in a tip portion thereof a narrower, outwardly projecting recess, filling the micropores with metal to form the metal microbodies each having at a tip portion thereof a projection made of the metal filled into the outwardly projecting recess, and removing at least part of the substrate from a metal microbody tip portion side to expose at least the projection at the tip portion of each of the metal microbodies. The resulting microstructure has metallic nanostructural elements that generate an enhanced electric field by an antenna effect at their pointed tips.
