Abstract
A method for manufacturing a metallic carrier base material having a multi-layer structure, if desired accommodated in a cylindrical case, for maintaining a catalyst for exhaust gas purification, wherein a multi-layer body having a number of screen-like vent holes in an axial direction is formed by piling up alternatively a planar band material and a corrugated band material made of thin nickel-plated steel strips, to furnish the contact portion. After inserting the multi-layer body into a cylindrical case, if desired, the multi-layer body or thus obtained composite is treated by immersion processing in a molten aluminum bath.
