A card connector includes an insulating housing having a signal terminal and a ground terminal arranged therein and a metal cover attached to the insulating housing for forming a card receptacle space therebetween. The metal cover is provided, at a rear end surface thereof, with a ground contacting portion and a holding portion disposed near the ground contacting portion. When the metal cover is attached to the insulating housing, the ground contacting portion of the metal cover contacts with a metal cover contacting portion of the ground terminal disposed in an opening of a ground terminal arranging portion of the insulating housing. Further, the holding portion of the metal cover engages an engagement portion of the insulating housing. Accordingly, it is possible to electrically connect the metal cover and the ground terminal with high reliability without increasing an outer size of the connector.
