Section: claims

1. A probe for a scanning type microscope which obtains substance information of a surface of a specimen by a tip end of a nanotube probe needle fastened to a cantilever, characterized in that a nanotube is fastened to said cantilever by a deposit of decomposed components produced by resolving an organic gas by use of an ion beam in a focused ion beam apparatus and scattering light molecules composing the organic gas. 2. The probe for a scanning type microscope according to  claim 1 , wherein said deposit comprises carbon atoms accumulated by using a hydrocarbon gas as said organic gas. claim 1 3. The probe for a scanning type microscope according to  claim 1 , wherein said deposit comprises metal atoms accumulated by nuns an organic-metallic gas as said organic gas. claim 1 4. The probe for a scanning type microscope according to  claim 1 , wherein said cantilever is coated with a conductive substance. claim 1 5. A probe for a scanning microscope produced by focused ion beam machining, characterized in that an unnecessary portion of a nanotube probe needle fastened to a cantilever is cut off by irradiating an ion beam at a tip end portion of said nanotube probe needle, and thus a length of said tip end portion of said nanotube probe needle is regulated to a predetermined length. 6. A probe for a scanning microscope produced by focused ion beam machining, characterized in that a part of nanotube components is charged by beaming ions at a tip end portion of a nanotube probe needle fastened to a cantilever, thus changing physical and chemical properties of said probe needle. 7. The probe for a scanning type microscope according to  claim 6 , wherein said ions are one selected from the group consisting of fluorine, boron, gallium, and phosphorus. claim 6 8. The probe for a scanning type microscope according to  claim 5 , wherein in cutting-off of said unnecessary portion, said nanotube is cut in an oblique direction thereof. claim 5
