1. An electrical connector which can engage with a corresponding connector inserted from a tip side thereof, comprising:
an insulating housing;
a first contact group constituted of a first plurality of contacts linearly extending along an insertion and extraction direction of the corresponding connector and held by the insulating housing so as to be arranged on a first contact plane;
a second contact group constituted of a second plurality of contacts linearly extending along the insertion and extraction direction of the corresponding connector and held by the insulating housing so as to be arranged on a second contact plane facing the first contact plane; and
a ground plate held by the insulating housing so as to be located on a ground plane facing the first contact plane and the second contact plane between the first contact plane and the second contact plane,
wherein each of the first contact group and the second contact group contains a signal contact pair constituted of two signal contacts for transmitting a differential signal,
wherein the ground plate has an opening facing the two signal contacts of the signal contact pair of each of the first contact group and the second contact group,
wherein a separation distance between outer side surfaces of the two signal contacts of the signal contact pair of the first contact group in an area facing the opening of the ground plate is larger than a width of the opening of the ground plate,
wherein the separation distance between the outer side surfaces of the two signal contacts of the signal contact pair of the first contact group in the area facing the opening of the ground plate is different from a separation distance between outer side surfaces of the two signal contacts of the signal contact pair of the second contact group in the area facing the opening of the ground plate, and
wherein a separation distance between inner side surfaces of the two signal contacts of the signal contact pair of the first contact group in the area facing the opening of the ground plate is smaller than the width of the opening of the ground plate.
