<P>PROBLEM TO BE SOLVED: To provide a current-carrying nut making electrical contact with a bolt screwed in the nut and improving the electrical contact performance with the bolt. Ž<P>SOLUTION: A groove for a conductive member is provided in an inner wall of a nut hole of a screw-thread-less nut section 14 to describe a circular shape along the nut hole inner wall. Material is used for the conductive member 26, which is deformed with the bolt screwed in the material and is incised with a screw groove. It is preferable to use a member which can be processed in a liquid state and be solidified after the processing. When the member able to be processed in a liquid state is used as the conductive member 26, the conductive member 26 is applied along the conductive member groove. When a member to be processed in a solid state is used as the conductive member 26, the conductive member 26 is fitted in the conductive member groove. An inner diameter of the circular shape formed by the conductive member 26 is almost equal to or smaller than a diameter of a screw groove of the screwed-in bolt. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
