PROBLEM TO BE SOLVED: To provide a switch element, magnetoregistance effect element, and memory device using carbon nanotubes, the deterioration of whose characteristics due to their miniaturization is prevented by a simple structure. SOLUTION: A substrate, a plurality of carbon nanotubes set on the substrate in a atanding way, magnetic substance particles arranged at the tip of each carbon nanotube, and a plurality of conductive layers formed between the tip end of each carbon nanotube and the substrate are prepared and structured, a difference in potential is caused between the conductive layers to bring into contact those magnetic substance effect particles arranged at the carbon nanotubes or at the tip of the carbon nanotubes, and current is applied between the carbon nanotubes with the carbon nanotubes or the magnetic substance effect particles in contact to perform a switch action by separating the nanotubes.
