Abstract: A socket connector includes: a socket housing; a plurality of contacts arranged in the housing; and a protective metal fitting configured to protect an island-like end part. The protective metal fitting includes: an upper-surface protective part covering an upper surface of the island-like end part; two crosswise surface protective parts extending downward from both ends of the upper-surface protective part in a width direction, and opposed to two crosswise side surfaces, respectively, of the island-like end part that face in the width direction; and two curling parts extending from lower ends of the two crosswise surface protective parts, respectively, in such a manner that the two curling parts get closer to each other as they extend.
