Description
板状の基体と、
基体の表面に形成されて相手コンタクトとの電気的な接触を担うパッドと、
パッドの縁に接して基体の表面に広がる保護膜とを有することを特徴とする。
パッドの、スライド方向前端の縁が、スライド方向に対し交わる幅方向に直線状に延びていることが好ましい。
パッドが、順次に間隔を空けてスライド方向に複数配列され、
保護膜が、スライド方向に複数配列されたパッドのうちの相対的に前方に配置された第1のパッドの後端の縁と第1のパッドの後方に隣接する第2のパッドの前端の縁との双方に接して、基体の表面に広がることが好ましい。
スライド方向に順次に間隔を空けてパッドが複数配列されてなる列がスライド方向に対し交わる幅方向に複数列配列され、
幅方向に隣接する2つの列に配列されたパッドが、スライド方向に互いに偏倚した位置に形成されていることが好ましい。
基体の、相手コンタクトがスライド方向後方に移動してきて保護膜に最初に接する側の前端部が、前方ほど厚みを減じるテーパ形状を有し、
保護膜が、その前端部を覆って広がっていることが好ましい。
