Abstract: According to various embodiments of the present invention, an electronic device comprises: a connector comprising a conductive shell and at least one terminal arranged inside the conductive shell; a capacitor; and a circuit board comprising a first board layer at least partially facing the connector, a second board layer formed beneath the first board layer, and at least one third board layer formed between the first board layer and the second board layer. The circuit substrate comprises: a ground area made of a conductor formed at least one of the first board layer, the second board layer, or the at least one third board layer and electrically connected to the conductive shell through the capacitor while being connected to a ground portion of the electronic device; a first conductive area which is a partial area of the first board layer facing the connector, the first conductive area being made of a conductor having a first size and electrically connected to the conductive shell; and a second conductive area which is an area of the second board layer at least partially facing the first conductive area with the at least one third substrate layer interposed therebetween, the second conductive area being made of a conductor having a second size wider than the first size and electrically connected to the first conductive area. At least one of the first conductive area and the second conductive area may be arranged adjacent to the ground area such that the first conductive area and the second conductive area are electrically separated from the ground area.
