1. An electronic device comprising:
a display comprising a first area and a second area;
a first housing supporting the first area and forming a first space on a rear surface of the first area;
a second housing supporting the second area and forming a second space on a rear surface of the second area;
a hinge structure connecting the first housing and the second housing to be foldable about a folding axis and allowing the first area and the second area to change between a first state in which the first area and the second area form substantially a same plane and a second state in which the first area and the second area face each other;
a first bracket connecting the first housing and the hinge structure and having a first opening penetrating through a surface thereof;
a second bracket connecting the second housing and the hinge structure and having a second opening penetrating through a surface thereof; and
a flexible printed circuit board (FPCB) extending from the first space to the second space across the folding axis in an extension direction,
wherein the FPCB comprises:
a central portion of which at least a portion is arranged on the hinge structure, first and second ends of the central portion extending to the first bracket and the second bracket, respectively;
a first sealing portion connected to the surface of the first bracket and sealing the first opening;
a second sealing portion connected to the surface of the second bracket and sealing the second opening;
