FINE STRUCTURE, OPTICAL MEMBER, ANTIREFLECTION FILM, WATER-REPELLENT FILM, SUBSTRATE FOR MASS SPECTROMETRY, PHASE PLATE, PROCESS FOR PRODUCING FINE STRUCTURE, AND PROCESS FOR PRODUCING ANTIREFLECTION FILM

摘要

Provided are an antireflection film having a high antireflection effect and a production process therefor, an optical member excellent in antireflection effect, a water-repellent film having excellent water repellency, a substrate for mass spectrometry having high detection sensitivity, a high-accuracy phase plate, and a fine structure that can be used in the foregoing and a production process therefor. The fine structure is a structure, including multiple conical portions on a surface thereof, in which the conical portions have a mesostructure; and the mesostructure includes a structure having mesopores.
