A picking facility includes a first conveyor for transporting a container that includes an opening portion provided on an upper side thereof and can contain an article, and a second conveyor for transporting a target article. The height level of a transport face of the first conveyor is set to be lower than the height level of a transport face of the second conveyor, and a difference between the height level of the transport face of the second conveyor and the height level of the transport face of the first conveyor is determined based on the height of the container.
