A card connector includes a base and a row of first upper terminals. The base has a top surface and a bottom surface and is formed with a card slot for receiving an electric card. The card slot has an insert port from which the electric card may be inserted. The upper terminals are arranged on the base. Each upper terminal has a contact positioned within the card slot for elastically contacting the inserted electric card, a pin extending out of the bottom surface of the base, and an extension connecting the contact to the pin. Each contact is convex toward the bottom surface of the base. Each contact is elastically biased toward the top surface of the base when contacting the electric card. Each pin extends out of the bottom surface of the base from a side opposite to the insert port of the card slot.
