HONEYCOMB STRUCTURE, ELECTRIC HEATING TYPE CATALYST CARRIER, AND EXHAUST GAS PURIFIER
To provide a honeycomb structure capable of suppressing crack on an end face of a honeycomb structure, an electric heating type catalyst carrier and an exhaust gas purifier.SOLUTION: A honeycomb structure 20 comprises: a ceramic honeycomb structure part 10 comprising, an outer peripheral wall 12, and a partition wall 13 which is arranged inside of the outer peripheral wall 12 and defines and forms multiple cells 16 forming a channel extending from one end face to the other end face; and a pair of electrode layers 14a, 14b which is arranged so as to extend in a belt-shape in a channel direction of the cells 13 across a central axis of honeycomb structure part 10 on an outer face of the outer peripheral wall 12. The honeycomb structure part 10 has; a low porosity part 4 which is arranged on an end part region which extends in a direction from at least one end face to a center of the honeycomb structure part 10 in a channel length direction, and the porosity is lower than average porosity of the whole honeycomb structure part 10.SELECTED DRAWING: Figure 1
【課題】ハニカム構造体の端面でのクラックの発生を抑制できるハニカム構造体、電気加熱式触媒担体及び排気ガス浄化装置を提供する。【解決手段】本発明によるハニカム構造体２０は、外周壁１２と、外周壁１２の内側に配設され、一方の端面から他方の端面まで延びる流路を形成する複数のセル１６を区画形成する隔壁１３とを有するセラミックス製のハニカム構造部１０と、ハニカム構造部１０の中心軸を挟んで、外周壁１２の外面上において、セル１３の流路方向に帯状に延びるように設けられた一対の電極層１４ａ、１４ｂと、を備え、ハニカム構造部１０が、少なくとも一方の端面からハニカム構造部１０の流路長さ方向中央に向かう方向に延びる端部領域に設けられ、気孔率がハニカム構造部１０の全体の平均気孔率よりも低い低気孔率部４を有している。【選択図】図１
