According to various embodiments of the disclosure, an electronic device may comprise: a housing including: a first surface, a second surface facing in a direction opposite to the first surface, and a side surface at least partially surrounding a space between the first surface and the second surface; a printed circuit board disposed between the first surface and the second surface; a first sensing element including a plurality of conductive vias arranged in parallel to the side surface in at least a portion of an edge of the printed circuit board; and a grip sensor electrically connected with the first sensing element. The grip sensor may be configured to detect a change in capacitance due to an approach or contact state of an external object to the housing, in at least a portion of the side surface of the housing using the first sensing element.
