A foreign material leaching apparatus using a filter is provided to prevent the production of scraps or powder when a work piece is pressed and to ensure smooth work even without removing the foreign material immediately. A leaching apparatus filters foreign materials by making a work piece pass through a separation hole(11) formed on a filter(10). A wide groove(12) is formed on the inside of the filter, and the separation hole is punched long from the inside of the wide groove to the outside of the filter so that the foreign materials unable to pass through the separation hole are inserted in the wide groove. A pressing unit(20) is provided to press the foreign materials flowing in the filter. |
