Electrical connector and electronic device

An electrical connector which can fit with a counterpart connector inserted from a tip side of the electrical connector, comprising:

• a plurality of contacts arranged in at least one plane;
• a first ground plate and a second ground plate facing the plurality of contacts and arranged so as to be separated from each other in a ground plane parallel to the at least one plane in which the plurality of contacts are arranged;
• and
• an insulator for holding the plurality of contacts, the first ground plate and the second ground plate in a state that the plurality of contacts, the first ground plate and the second ground plate are insulated from each other,
• wherein the first ground plate includes a plate-like main body portion and a first extending portion extending from the main body portion thereof toward the second ground plate,
• wherein the second ground plate includes a plate-like main body portion and a first extending portion extending from the main body portion thereof toward the first ground plate,
• wherein the first ground plate and the second ground plate are arranged in the ground plane so that the main body portion of the first ground plate and the main body portion of second ground plate face each other through a center line of the electrical connector in a width direction of the electrical connector perpendicular to an insertion direction of the counterpart connector, and
• wherein the first extending portion of the first ground plate extends from the main body portion of the first ground plate toward the main body portion of the second ground plate over the center line of the electrical connector in the width direction of the electrical connector and the first extending portion of the second ground plate extends from the main body portion of the second ground plate toward the main body portion of the first ground plate over the center line of the electrical connector in the width direction of the electrical connector, and thereby an area in which the first extending portion of the first ground plate and the first extending portion of the second ground plate are overlapped with each other in the insertion direction of the counterpart connector is formed.
