Abstract
A carrier for exhaust-gas purification is able to effectively protect against getting clogged with the particulate matters in a filter having carriers. The carrier is constituted with a web corrugated to have straight and/or zigzag ridges and then wound up into a column. The carrier for exhaust-gas purification is made of the web of wire netting or nonwoven metallic fabric, which is embossed to have ridges and grooves extending at least in a widthwise direction and further wound up spirally or stacked on top of the other into the column.
