An electronic device according to various embodiments of the present disclosure may include: a printed circuit board including one face; at least one electronic component mounted on the printed circuit board; and a conductive shield can structure attached to the one face of the printed circuit board while surrounding the at least one electronic component. The conductive shield can structure may include: a first conductive plate including a first edge portion, a second edge portion spaced apart from the first edge portion, and a third edge portion extending between the first and second edge portions, and in top view of the one face of the printed circuit board, including a first flat portion parallel to the printed circuit board and constructing a recess together with the first to third edge portions; a second conductive plate including a fourth edge portion extending substantially parallel to the third edge portion, and in top view of the one face of the printed circuit board, including a second flat portion to be attached to the first flat part while at least partially overlapping the first flat portion; a first side portion extending along the first edge portion and substantially vertical to the first flat portion; a second side portion extending along the second edge portion and substantially vertical to the first flat portion; and a third side portion bent from the fourth edge portion while surrounding the third edge portion, and substantially vertical to the first flat portion.
