摘要： A tubular body extending in a longitudinal direction and having conductivity includes a first spring portion having a spiral notch formed in a peripheral surface of the tubular body, a second spring portion having a spiral notch formed in the peripheral surface of the tubular body and a first body portion sandwiched between the first spring portion and the second spring portion in the longitudinal direction. The distance from the longitudinal direction center of the tubular body to the longitudinal direction inner end of the first spring portion is equal to the distance from the longitudinal direction center to the longitudinal direction inner end of the second spring portion. The number of turns of the first spring portion is equal to the number of turns of the second spring portion. The first spring portion includes a first winding spring portion whose winding direction is a first direction and a second winding spring portion whose winding direction is a second direction opposite to the first direction.

摘要： A contact terminal includes a tubular body Pa being tubular, and made of an electrically conductive material; and first and second central conductors Pb and Pc each of which is made of an electrically conductive material, and is in the shape of a stick. The first and second central conductors Pb and Pc include first and second stick-shaped bodies Pb1 and Pc1, first and second clasped portions Pb2 and Pc2 each of which is configured to have a diameter greater than that of each of the first and second stick-shaped bodies Pb1 and Pc1, and first and second swell portions Pb6 and Pc6 each of which is configured to have a diameter greater than that of each of the first and second stick-shaped bodies Pb1 and Pc1. The first and second central conductors Pb and Pc are arranged to have a distal end portion of each of the first and second swell portions Pb6 and Pc6 inserted into a joining portion Pf of the tubular body Pa, and to have a distal end surface of the first swell portion Pb6 and a distal end surface of the second swell portion Pc6 kept opposite to each other with a gap therebetween.
