Abstract: A plurality of retaining piece portions are formed at an edge of a tubular body of a female electrical connection member, and the retaining piece portions are bent to clampingly retain plural portions in one end of a resilient contact piece. As a result, the retaining piece portions can be bent easily, and a crack is prevented from developing at the bent portion. And besides, since the resilient contact piece is fixed by the retaining piece portions at the plurality of portions thereof spaced from one another, stresses, concentrating on the fixed portions of the resilient contact piece, are distributed on the fixed portions, so that permanent set of the resilient contact piece due to deterioration of its resiliency can be prevented.
