A card connector (1) is disclosed. The card connector (1) comprises a housing (11), at least one terminal (51), a card guiding mechanism and an identification switch. The housing (11) is configured to accommodate a card adapter (101), in which a first card (201) is fitted, or a second card (301). Each of the at least one terminals (51) is attached to the housing (11). The card guiding mechanism includes an urging member (81). The urging member (81) is configured to urge the card adapter (101) or the second card (301) in a direction opposite to an insertion direction. The card guiding mechanism is configured to hold in a lock position the card adapter (101) or the second card (301) pushed in the insertion direction by way of push operation. The identification switch is formed by a first contact member (52) and a second contact member (53), and is arranged further inward in the insertion direction from an insertion direction front end (301a) of the second card (301) held in the lock position. The identification switch is configured to identify the card adapter (101) and the second card (301). The card adapter (101) has a front projection (103) extending forward from an insertion direction front end (101a). The first contact member (52) is displaced in the thickness direction of the card adapter (101) and comes into contact with the second contact member (53) when abutting against the front projection (103) of the card adapter (101).
