Abstract: The invention provides: an exhaust-gas-purifying metal substrate capable of achieving both low pressure loss and high purification performance; and an exhaust gas purification device using the metal substrate. The invention relates to an exhaust-gas-purifying perforated metal substrate in which a corrugated foil and a flat foil are layered and made into a cylindrical shape, wherein: the perforated metal substrate includes from 50/in2 to 800/in2 of cells; the corrugated foil includes a plurality of first holes having an area that is from 2.0 to 50 times the average opening area of the cells; the flat foil includes a plurality of second holes having an area that is from 3.0 to 100 times the average opening area of the cells; and the average value of the area of the first holes in the corrugated foil is smaller than the average value of the area of the second holes in the flat foil.

Abstract: A perforated metallic base material for purging exhaust is obtained by laminating a wavy foil having pores and a flat foil having pores and forming the same into a cylindrical shape, wherein the wavy foil and/or the flat foil has axially perforated portions having pores throughout the axial direction of the cylindrical shape and axially non-perforated portions not having pores overall in the axial direction of the cylindrical form.
