An electronic device is disclosed. The electronic device may include a housing and a camera module, a first camera housing enclosing a camera assembly, the camera assembly including a second camera housing enclosing a lens carrier having at least one lens, and an image sensor. The second camera housing includes a first surface, a second surface, at least one side area surrounding a space defined between the first and second surface, and at least one corner area. The camera assembly is rotatable about the camera assembly, so that an optical axis of the lens is angled at a predetermined angle with respect to the first direction. The side area is spaced by a first gap from an inner surface of the second camera housing, and the at least one corner area is spaced by a second gap from the inner surface of the second camera housing.
