PURPOSE:To obtain the title substrate on which a stable bimolecular membrane of good reproducibility can be formed and by which the interaction between the bimolecular membranes can be freely controlled by constituting it from a thin metal sheet having a plurality of small throughholes and the inside wall of whose pores and the surface around small holes are selectively made hydrophobic. CONSTITUTION:A thin metal (e.g. Ni) sheet having at least two small throughholes by, for example, an electric field deposition is made, and SiO2 is formed on both sides on the thin sheet 1 by high-frequency sputtering. The boundary regions on the surfaces of this thin sheet 1 are masked to separate small pores into individuals 2, treated with a hydrophobic agent (e.g. hexamethyldisilazane) in a vapor phase to make it hydrophobic to obtain the title substrate constituted of a thin metal sheet which has at least two small throughholes and on which the inside walls of the small pores and the surfaces around them are selectively made hydrophobic.
