Abstract: A manufacturing method of a probe according to the present embodiment is used to manufacture a probe for a scanning probe microscope. An insulating film is formed on the surface of a probe provided on a base. Metal ions are implanted into the insulating film. An electric field is applied to the insulating film to concentrate the metal ions in the insulating film at a tip of the probe and form a metallic filament in the insulating film.
