FILTER BODY OF FILTER APPARATUS, FILTER APPARATUS USING THE SAME AND METHOD FOR MANUFACTURING FLAT PLATE FOR FILTER BODY

PROBLEM TO BE SOLVED: To inexpensively provide a filter body formed by laminating flat plates and a filter body comprising a densely wound coil or to provide a filter apparatus using these filter bodies. SOLUTION: A spacer or the like is formed to each of the flat plates by a printing method and the flat plates are stacked so that the surfaces having the spacers of the flat plates are turned in the same direction and both end surfaces thereof are closed to form the filter body. Alternatively, the spacer is provided in the flat plate by the printing method and this flat plate is cut into a wire material and the wire material is densely wound in a coil form so that the surface having the spacer of the wire material comes into contact with the wire material and the lower end of the formed coil is closed to form the filter body. These filter bodies are used to constitute the filter apparatus. COPYRIGHT: (C)2003,JPO
