A fluid transmitting polyolefin foam having a special open-cell cellular structure as compared with the conventional polyolefin foams having all cells closed is disclosed. Such a novel fluid transmitting polyolefin foam is produced by mixing a polyolefin with a polymer other than a polyolefin, said polyolefin and/or said polymer other than a polyolefin having a blowing agent incorporated therein and/or adhered thereto and subjecting the resulting mixture to extrusion moulding. The present fluid transmitting polyolefin foam has a wide variety of uses, for example, as a synthetic leather, synthetic filter cloth, separator of storage battery, synthetic paper, package, etc.
