1. A fastening structure comprising:
a first structural member including a first carbon fiber reinforced plastic inner layer and a first non-electrically-conductive composite material outer layer stacked on the first carbon fiber reinforced plastic inner layer in a first direction, the first carbon fiber reinforced plastic inner layer including carbon fibers extended in a second direction substantially perpendicular to the first direction, the first non-electrically-conductive composite material outer layer including fibers extended in a third direction substantially perpendicular to the first direction;
a second structural member having a second inner surface, the second inner surface being in direct surface contact with a first inner surface of the first carbon fiber reinforced plastic inner layer facing the first direction, such that the second inner surface and the first non-electrically-conductive composite material outer layer sandwich the first carbon fiber reinforced plastic inner layer in the first direction, the second inner surface having electric conductivity; and
a fastening member penetrating the first inner surface and the second inner surface along the first direction, and fastening the first structural member and the second structural member,
wherein the first carbon fiber reinforced plastic inner layer includes an electrically-conductive polymer, an electrically-conductive resin or a carbon nanotube so that a conductivity of the first carbon fiber reinforced plastic inner layer in the first direction is higher than a conductivity of the first non-electrically-conductive composite material outer layer in the first direction.
