Electronic device including connection structure for electrically connecting printed circuit board and housing

Disclosed is an electronic device that includes a first cover, a second cover opposite the first cover, a side housing disposed between the first cover and the second cover and including a plate disposed between the first cover and the second cover and a frame surrounding the plate and connected with the first cover and the second cover, a display disposed between the plate and the first cover, and a printed circuit board disposed between the plate and the second cover and including a first surface facing the plate, a second surface facing the second cover, and side surfaces provided between the first surface and the second surface, at least some of the side surfaces including plated areas. The plate includes a connection structure to which the printed circuit board is electrically connected, the connection structure includes a recess, the recess including a first sidewall, a second sidewall facing the first sidewall, a first conductive structure comprising a conductive material disposed on the first sidewall, and a second conductive structure comprising a conductive material disposed on the second sidewall, and at least part of the printed circuit board is disposed in the recess such that the plated areas contact the first conductive structure and the second conductive structure.
