A structure includes a conductive film ( 12 ) provided in an underlying layer ( 10 ); and a carbon nanotube bundle ( 20 ) including a plurality of carbon nanotubes each having one end connected to the conductive film ( 12 ), wherein, at other end side of the carbon nanotube bundle ( 20 ), at least carbon nanotubes allocated at outer side of the carbon nanotube bundle ( 20 ) extend with convex curvatures toward the outside of the carbon nanotube bundle ( 20 ), and the convex curvatures of the carbon nanotubes allocated at the outer side of the carbon nanotube bundle are larger than those of inner side of the carbon nanotube bundle ( 20 ), and diameters of the carbon nanotube bundle ( 20 ) decrease toward the other end of the carbon nanotube bundle ( 20 ). |
