An IC card has a card substrate having semiconductor integrated circuit chips mounted thereon and a plurality of connector terminals formed thereon. The connector terminals are exposed from a casing. The connector terminals are laid out in plural sequences in staggered form between sequences adjacent to one another forward and backward as viewed in an IC card inserting direction.
