<p>A capillary member (11) comprising a disc-shaped plate unit (15) and a tubular edge glass unit (17), the plate unit (15) having a plurality of through holes (13) arranged regularly and two-dimensionally. This capillary member (11) is characterized in that a plurality of dual-tubes, each consisting of an inner tube of a first glass material formed with through holes and an outer tube of a second glass material, are bundled, and the outer tubes are fused to each other to be formed into a plate shape. The first glass material is larger in linear expansion coefficient than the second glass material, and is higher in softening temperature, yield temperature and glass transition temperature than the second glass material, thereby providing high strength and porosity.</p> |
