Heat transfer member and electronic device including the same

An electronic device, comprising:

• a housing including a front plate facing in a first direction, a back plate facing in a second direction opposite to the first direction, a supporting member disposed between the front plate and the back plate to form a space, a first area dividing the space along a lengthwise direction from an end of the supporting member, and a second area positioned adjacent to the first area and dividing the space in parallel with the first area;
• a printed circuit board on which a plurality of electronic components are mounted, the printed circuit board being disposed in the first area, and including a first printed circuit board on which a first plurality of electronic components are mounted and a second printed circuit board at least partially overlapping the first printed circuit board and electrically connected with the first printed circuit board;
• a battery disposed in the second area;
• and
• a first heat transfer member including a partial area that faces at least one electronic component among the first plurality of electronic components mounted on the first printed circuit board and at least another partial area that is bent and faces another electronic component among the first plurality of electronic components mounted on the first printed circuit board.
