<p><P>PROBLEM TO BE SOLVED: To provide a structure pressing an electronic component on a circuit board to detachably mount it with low contact resistance wherein the electronic component includes a first electrode having carbon nanotubes implanted thereto. <P>SOLUTION: A circuit board 1 has a second electrode 11 formed on the circuit board 1, wherein a tip of each of carbon nanotubes 23 contacts with the second electrode 11, so that the second electrode 11 is electrically connected with a first electrode 21. The second electrode 11 has: an electrode pad 12 disposed on an upper surface of the circuit board 1; and conductive cone-shaped projections 13 formed on an upper surface of the electrode pad 12 in a frog-like shape. Since each carbon nanotube 23 contacts linearly with each projection at a side surface of each carbon nanotube 23, low contact resistance is achieved even by pressing at a low pressure within an elastic limit of the carbon nanotubes 23. In addition, since no plastic deformation occurs in the carbon nanotubes 23, reconnection can be performed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
