摘要： A method for applying a carbon nanotube growth catalyst to at least one specified location on a substrate surface of a substrate formed of conductive material, and the method includes a preparation step for preparing on the substrate a coating layer having a hole contacting the substrate surface at a location corresponding to the specified location. The method also includes a deposition step for forming by deposition a conical deposited material on a substrate surface portion contacting the hole by irradiating the substrate with electrically conductive material particles in a oblique direction from above the coating layer while rotating the substrate about a shaft perpendicular to the substrate surface, and for forming by deposition an eaves-like deposited layer which extends to close an opening of the hole. The method also includes a determination step for measuring a size of the opening in accordance with extension of the eaves-like deposited layer, and a catalyst applying step for applying the catalyst to a tip of the conical deposited material by way of irradiation of material particles of the catalyst via the opening when the opening is measured to have a specified size.
