Abstract

　ハニカムセグメント２は、長手方向に垂直な平面で切断した断面における断面積が異なる２種類のセル５ａ，５ｂが形成されている。第１のセル（大セル）５ａは、セルの長手方向に垂直な平面で切断した断面における断面積が第２のセル（小セル）５ｂの断面積よりも大きく、角部に相当する部分が切り落とされた八角形状または角部に相当する部分が円弧状の四角形状に形成されており、第２のセル（小セル）５ｂは、四角形状に形成されている。第１のセル５ａと、その第１のセル５ａに隣接する第１のセル５ａとの１－１セル間壁の壁厚は、第１のセル５ａと、その第１のセル５ａに隣接する第２のセル５ｂとの１－２セル間壁の壁厚よりも大きく形成されている。本発明のハニカムフィルタは、隔壁における流体の流通を向上させることにより捕集性能を向上させるとともに、強度も増加させることができる。
