PURPOSE:To perform continuous and efficient work, by providing a plurality of a developing liquid surfaces to a membrane forming apparatus and forming a membrane to at least one liquid surface and supplying a membrane forming molecular group to at least the other one liquid surface. CONSTITUTION:A partition 14 is rotated to the direction opposite to an arrow to widen a developing liquid surface and a membrane forming molecular group is dripped on the liquid surface A from a dripping nozzle 17. Next, the partition 14 is rotated to the direction shown by the arrow to reduce the area of the developing liquid surface A and pressure is applied to the membrane forming molecular group. When the membrane forming molecular group shows set sur face pressure and a monomolecular membrane is formed, the monomolecular membrane is built up on a substrate 7. Because the area of the developing liquid surface A is reduced as the transfer of the monomolecular membrane advances, a membrane forming molecule tank 16 is rotated to the side of a developing liquid surface B and the membrane forming group is dripped on the liquid surface B from the dripping nozzle 17. Hereinafter, the same operation as that in the developing liquid surface A is performed to enable the continuous formation of the membrane.
