An electronic device is provided. The electronic device includes a first housing structure, a second housing structure, a hinge structure rotatably connecting the first housing structure and the second housing structure and including a first hinge plate and a second hinge plate, a hinge cover covering at least part of the hinge structure when the hinge structure is viewed from the outside, and a flexible printed circuit board crossing the hinge structure and extending from an inside of the first housing structure to an inside of the second housing structure and including a pair of fixing members to permit deformation of the flexible printed circuit board in the internal space of the hinge cover, wherein the hinge structure includes a first member attached to the first hinge plate, and a second member attached to the second hinge plate, and wherein the first member and the second member are disposed to face the flexible printed circuit board so as to prevent direct contact between the hinge structure and the printed circuit board during folding and/or unfolding of the electronic device.
