ただし、hは前記ハニカム体の軸方向における孔の配置間隔であり、pは前記軸方向に対して直交する方向であって、かつ、箔に沿う方向における孔の配置間隔である。
図1は触媒コンバータ1の斜視図である。触媒コンバータ1は、平箔2と波箔3を巻きまわしてなるハニカム体4と、当該ハニカム体4の外周面を囲む外筒5とを有する触媒担持用基材において、触媒をハニカム体4に担持させることによって構成されている。平箔2及び波箔3には、耐熱合金からなる金属箔を用いることができる。金属箔の膜厚は、好ましくは20μmから100μmである。波箔3は、金属製の平箔を例えばコルゲート加工することによって製造することができる。
金属箔の箔厚は50μmに設定した。外筒の肉厚は1.5mmに設定した。平箔及び波箔を重ね合わせた状態で巻き回すことにより、直径50mm、長さ80mm、セル密度1インチあたり300セルのハニカム体を得た。
