A method of forming a lipid planar membrane of a bilayer membrane composed of lipid and protein comprises the step of immersing a substrate (10), which has a long-chain hydrocarbon group at least on the surface of one side thereof, in a suspension of liposome or proteoliposome (20), respectively. The long-chain hydrocarbon group is introduced into the substrate by bonding a long-chain alkylsilane coupling agent or a long-chain alkyltitanate coupling agent.
