1. An electronic device comprising:
a housing including a first end disposed on one end thereof; and a second end disposed on another end thereof opposite to the first end;
a nib disposed in the housing, the nib including a pen tip protruding to an outside through the second end and a dielectric coil wound multiple times therein;
a printed circuit board electrically connected to the dielectric coil;
a board seating part which is at least partially coupled to the nib and in which the printed circuit board is seated;
an elastic member seating part disposed in the housing such that the elastic member seating part and the board seating part are at least partially fitted to each other; and
an elastic member disposed between the elastic member seating part and the board seating part,
wherein the nib, the board seating part, the elastic member, and the elastic member seating part are sequentially arranged in the housing,
wherein, in response to the nib being pressed in a direction toward an inside of the housing by a pen pressure, the pen pressure is transmitted to the elastic member via the board seating part, and the nib and the board seating part move in a first direction from the second end toward the first end as the elastic member is compressed by the pen pressure, and
wherein in response to the pen pressure being released, the nib and the board seating part are returned in a second direction opposite to the first direction by restoring force of the compressed elastic member.
