ABSTRACT The invention to provide a chemically adsorbed monomolecular lamination film comprising a chemically adsorbed monomolecular film formed via a siloxane-based monomolecular or polymer film on a substrate surface. It also seeks to provide a method of forming a chemically adsorbed monomolecular film efficiently and with high density on a substrate surface with few hydroxyl groups, which method comprises a step of contacting a substrate containing hydroxyl groups present on the surface with a non-aqueous solution containing a material with plural chlorosilanol groups in molecule, a step of removing the material remaining on the substrate without reaction by washing the substrate with a non-aqueous organic solution (if this process is omitted, the siloxane-based polymer film is prepared on the substrate), a step of forming a monomolecular film constituted by a compound containing a silanol group in molecule on the substrate by exposing to the air containing moisture or washing with water, after the removal step, and a step of laminating a monomolecular adsorption film by adosorbing a chlorosilane-based surface active agent constituted by a straight hydrocarbon chain having a chlorosilane groups at one end onto the substrate after the monomolecular or polymer film formation step.
