前記高周波信号は、ミリ波信号である。
前記挿抜方向(Z軸方向)から平面視するとき、前記接触部32,34,36,38の周方向の間隔が、前記ミリ波信号の波長の半分以下である。
前記挿抜方向(Z軸方向)と直交し、前記第1接続端子12および前記第2接続端子22が位置する側面方向(X軸方向)から側面視するとき、前記第1高周波用接続端子15は、前記第2外部接地部材26と重ならない非重畳部15aを有し、前記非重畳部15aと重ならない側方切欠部33bが前記第1外部接地部材16に形成されており、前記側方切欠部33bでの前記挿抜方向(Z軸方向)と前記側面方向(X軸方向)とに直交する第3の方向(Y軸方向)の切欠長さAが、前記ミリ波信号の波長の半分以下である。
前記第1コネクタ10において、前記第1外部接地部材16が複数個配設され、2つの前記第1外部接地部材16,16の間に、前記第1接続端子12が配設される。
