摘要：
A metal substrate for catalytic converter for purifying an exhaust gas includes a honeycomb core with metal flat foil and corrugated foil stacked in layers, and an oxide film having a thickness of 0.1 μm or more and 10 μm or less is formed in a predetermined range including an exposed end surface exposed toward the gas inlet side. The oxide film contains at least a first alumina including α-alumina and a Fe oxide. The α-alumina contains α-alumina with solid-solved Fe and α-alumina with no solid-solved Fe. In the oxide film, the content of the first alumina is 30% by mass or more and 99.5% by mass or less, the content of the Fe oxide is 0.5% by mass or more and 40% by mass or less, and the content of Fe is more than 7% by mass and 35% by mass or less.
