PURPOSE:To suppress closing of plural paths of a porous carrier. CONSTITUTION:A flat plate 1 and a corrugate plate 2 are laminated and wound to form paths 4 between them and to form a metal body 3. In the one end of the metal body 3, contact points between the flat plate 1 and the corrugate plate 2 are joined in a manner that not all of the contact points are joined but part of them are joined. By this constitution, thermal expansion and contraction are repeated by cooling and heating cycles on the metal body, which give stress on the metal body 3. The stress can be relaxed by movements of the flat plate 1 and the corrugate plate 2 in the region where the contact points are not joined. |
