ABSTRACT:
A porous support of the present invention comprises a laminate which is formed by laminating a corrugated sheet, in which high and low wave portions coexist, and a flat sheet, and which is wound into a spiral form. The porous support is particularly used as a catalyst support for purifying automobile exhaust gas. Appropriate combination of the high and the low wave portions in the corrugated sheet permits the selection of any one of various cross-sectional forms such as a conventional circular form, a race track-like form, a broad bean-like form, a triangular form and other suitable forms. The degree of freedom of the form can be thus increased.
