Abstract
Abstract A transfer material comprising an organic thin film uniformly provided by a wet method, etc. with high productivity is used to efficiently produce an organic thin film device such as an organic EL device excellent in light-emitting efficiency, uniformity of light emission and durability. A method for producing the organic thin film device according to the present invention comprises the steps of: making an organic thin film 112 of a transfer material 110 face a transparent electrically conductive layer 102 disposed on a support 101, the transfer material 110 having the organic thin film 112 on a temporally substrate 111; decompressing a space 105 between the transfer material 110 and the transparent electrically conductive layer 102 to bring the transfer material 110 in contact to the transparent electrically conductive layer 102; heating at least one organic thin film 112; and peeling the temporary substrate 111 from the organic thin film 112 to transfer the organic thin film 112 to the transparent electrically conductive layer 102.
