PROBLEM TO BE SOLVED: To provide a catalyst carrier which has excellent durability and oxidation resistance, and to provide Al-containing highly oxidation resistant stainless steel foil which is suitable as the stock therefor, and has no wrinkling on joining such as brazing. SOLUTION: The Al-containing highly oxidation resistant stainless steel foil has a composition comprising, by mass,≤0.10% C, 0.05 to 2.0% Si,≤0.5% Mn, 14.0 to 30.0% Cr, 1.5 to 10.0% Al,≤0.10% N and 0.01 to 0.30% Zr. The sheet thickness t is controlled to 15 to 100μm, and also, the thermal expansion coefficient A(/°C) on brazing joining treatment is controlled to the following range in accordance with the sheet thickness t. The controlling range is shown in the formulae: when 40≤t100 (μm), A(/°C)≤13.0×10<SP>-6</SP>and when 15≤t40 (μm), A(/°C)≤(0.05t+11.0)×10<SP>-6</SP>. COPYRIGHT: (C)2004,JPO&NCIPI
