To provide a method for producing a linear nanomaterial, capable of easily conducting control of a wall thickness and multilayer formation, to provide the linear nanomaterial produced thereby, and to provide a thin film transistor substrate given by utilizing the linear nanomaterial.
This method for producing the linear nanomaterial includes a process for preparing a template in which pore spaces having a diameter of not more than 200 nm are formed and a process for introducing an organic substance of a gas phase into the pore spaces and forming the linear nanomaterial therein. The linear nanomaterial thus produced has a diameter of not more than 200 nm and comprises a tubular shell of which the inside is hollow and a core which is formed inside the shell.
