Foldable electronic device comprising flexible display

An electronic device according to various embodiments can provide a structure capable of imparting a physical optical effect to a camera unit of a foldable electronic device to which a flexible display is applied. An electronic device according to various embodiments may comprise: a lens unit placed in a partial area of a first side, which does not include a flexible display, through the first side and a second side; a first imaging unit which, when the first side is divided into a first area and a second area on the basis of an axis, is placed adjacent to the first area in which the lens unit is placed; and a second imaging unit which is placed in at least a partial area of the second side and is configured to be combined on the same optical axis with the lens unit when the electronic device is folded on the basis of the axis. In addition, other embodiments are possible.
