Abstract

　流体の入口側と出口側とで開口率が異なるハニカム構造体であって、開口率の高い入口側の構造的な剛性が高いハニカム構造体を提供する。 　端面の面積が異なる２種類の貫通孔４（４ａ，４ｂ）、５（５ａ，５ｂ）が隔壁６を隔てて複数併設されて柱状のハニカムセグメント３が構成され、該ハニカムセグメント３は、一方の端面においては、端面の面積の小さい貫通孔５ｂが目封止されて開口率が高い入口側が形成され、他の端面においては、端面の面積が大きい貫通孔４ｂが目封止されて開口率が低い出口側が形成されており、複数の前記ハニカムセグメント３が接合材２を介して、長手方向の向きを揃えて固着されて構成されるハニカム構造体であって、入口側の端面の接合材２の接合幅が出口側の端面の接合材の接合幅よりも大きいハニカム構造体１である。
