A juice extractor, which is configured in such a way that the cross-sectional area of a feed tube is larger than the cross-sectional area of a feed port of a hopper, so that an input material that is used to make juice and which is put into the feed port can be directly dropped onto the lower portion of the feed tube without staying in the feed tube, thereby allowing a user to easily make juice without having to manually push the input material using a pusher.
