Abstract: A receptacle terminal includes a cable connection portion 31 connected to a cable, and a contacting portion 2 insertion-connected to a tab terminal. The contacting portion 2 has a flat part 21 of a particular area, and a pair of sideplate parts 23, 23 of a particular length that stand up in the same direction from the two sides of the flat part and oppose each other at a particular spacing. The lower portion of the opposed surfaces of such pair of sideplate parts 23, 23 is cut and lifted out to form spring pieces 24, 24 which remains joined to the sideplate at the top. Such spring pieces are bent toward each other, forming a gap between the bottom edge of each spring piece and the flat part, and the tab terminal 4 is inserted into such gaps. A simple structure and strong elastic contacting force are provided.
