    • An electronic device may include: a first housing; a second housing that is foldably coupled, directly or indirectly, to the first housing through a hinge device; a display disposed to be supported by at least the first housing and the second housing; a digitizer disposed under the display; a first printed circuit board disposed at least partially in a first inner space of the first housing and electrically connected, directly or indirectly, to the digitizer; a second printed circuit board disposed at least partially in a second inner space of the second housing and electrically connected, directly or indirectly, to the digitizer; a third FPCB structure electrically connecting the first printed circuit board and the second printed circuit board; and a processor that detects the coordinates of an electronic pen that is close to the digitizer. The digitizer may include a first electro magnetic resonance (EMR) sheet disposed at least partially in the first inner space of the first housing and including a first flexible printed circuit board (FPCB) structure and a second EMR sheet disposed at least partially in the inner space of the second housing and including a second FPCB structure. The digitizer may include a plurality of x-axis channels and a plurality of y-axis channels orthogonal to the plurality of x-axis channels, and the plurality of x-axis channels may include single channels formed of single wires and common channels formed of common wires.
