A card connector is disclosed having a base and a plurality of contacts. The plurality of contacts is positioned on the base. Each of the contacts has a contacting portion electrically contacting an electrical card when the electrical card inserted into the card connector. Each contact has an outer facing surface, and a supporting portion having two elastic arms extending from the base and intersecting at the contacting portion. Each of the elastic arms has a guide arm portion extending from the contacting portion at an angle of approximately 0 to 90 degrees with respect to a card insertion direction. Each guide arm portions has a smooth, ridge-shaped convex surface extending to the contacting portion and a smooth transitional surface with the outer facing surface of the contacting portion.
