PROBLEM TO BE SOLVED: To provide a forming method of a multi-layered silicon nanotube having a structure based on two-dimensional structure, and the multi-layered silicon nanotube formed by the forming method. SOLUTION: The multi-layered silicon nanotube, which comprises a pseudo-two-dimensional sheet having silicon element as a main component, which is constituted by concentrically superposing several silicon layers having cylindrical shapes different in diameter, and in which the interlayer distance of the silicon layers is 0.36±0.02 nm, is formed by placing a silicon target 4 in a chamber 1, and convergently irradiating the surface of the silicon target 4 with a laser light 11.
