Abstract: A foldable electronic device includes a display including a first and second areas; a first and second housings; a hinge structure foldably connecting the first housing and the second housing to each other on a folding axis; a flexible printed circuit board (FPCB) extending across the folding axis from a first space between the first housing and the display to a second space between the second housing and the display and including a first bending portion and a second bending portion; a sensor configured to identify an impedance in the FPCB; and a processor configured to identify a folding angle between the first housing and the second housing based on the impedance. The first bending portion includes a first sensing pattern part including a first pattern forming a first electrical path and a second pattern forming a second electrical path.
