The silicon film may be a film wherein the diameter of the columnar structures is from 10 nm to 100 nm and the film thickness is from 0.2 μm to 100 μm. In the process for preparing a silicon film on a substrate by vapor deposition using a vapor deposition source made of Si or a Si compound, the temperature of the vapor deposition source is 1700 K or higher, the temperature of the substrate is lower than that of the vapor deposition source, and the temperature difference between the vapor deposition source and the substrate is 700 K or larger. In the process for preparing the silicon film, the distance (D) between the vapor deposition source and the substrate is shorter than the minimum diameter (P) of the substrate, the minimum diameter (P) being determined by viewing the substrate from the perpendicular direction. Also provided are an electrode comprising the silicon film, and a lithium secondary battery comprising the electrode as a negative electrode.
