A connector is capable of selectively connecting different types of cards. The connector has a first connector portion having a first contact for connection to a first card, and a second connector portion having a second contact for connection to a second card. The first contact and the first card are connected together in a fitting/removal direction, while, the second contact and the second card are connected together in a direction crossing the fitting/removal direction. When the first contact and the first card are connected together, the second contact is prevented from contacting the first card. When the second contact and the second card are connected together, the first contact is prevented from contacting the second card.
