• a ground terminal disposed at a rear end portion of the insulating housing for contacting the ground contact portion when the card is inserted into the card receptacle space;
• a signal terminal arranging portion disposed at the rear end portion of the insulating housing for arranging the signal terminal;
• and
• a ground terminal arranging portion disposed at the rear end portion of the insulating housing for arranging the ground terminal;
• wherein said ground terminal includes,
• a connecting portion to be connected to a ground conductor of a circuit board which the card connector is to be mounted on,
• a first elastic arm portion extending from the connecting portion toward a front side of the card receptacle space,
• a card contacting portion at a distal end of the first elastic arm portion for contacting with the ground contact portion, and
• a metal cover contacting portion disposed between the first elastic arm portion and the connecting portion;
• said metal cover includes,
• a ground contacting portion disposed at a rear end surface thereof, and having a second elastic arm portion extending from the metal cover and a contacting portion disposed at a lower end portion of the second elastic arm portion, and
• a holding portion disposed near the ground contacting portion, and having a holding arm portion extending downwardly from the upper surface of the metal cover and an engaging portion disposed on the holding arm portion;
• and
• said insulating housing includes,
• an engagement portion disposed at a position corresponding to the engaging portion for engaging the engaging portion so that the contacting portion contacts with the metal cover contacting portion when the metal cover is attached to the insulating housing.
