HONEYCOMB STRUCTURAL BODY, EXHAUST GAS PURIFICATION DEVICE, EXHAUST SYSTEM, AND METHOD FOR PRODUCING HONEYCOMB STRUCTURAL BODY
Provided are a honeycomb structural body and an exhaust gas purification device that are capable of burning off and removing carbon particulates by means of electric heating, that can be used at a position where condensate water is generated, that are free from short circuiting due to condensate water or carbon deposition, and that exhibit low pressure loss. This honeycomb structural body has a columnar shape and has: porous partition walls which provide flow channels for a fluid and which partition off and form a plurality of cells extending from an inflow end face, which is the end face disposed on the inflow side of the fluid, to an outflow end face, which is the end face disposed on the outflow side of the fluid; and an outer peripheral wall disposed at the outermost periphery. The partition walls each have a superficial layer that is provided to at least a portion of the surface of the partition wall. The superficial layer includes magnetic particles and has air permeability.
本发明提供蜂窝结构体及废气净化装置，能够利用电加热将碳微粒等燃烧除去，并且，即便在产生冷凝水的位置也能够使用，不存在由冷凝水或碳堆积所引起的短路问题，压力损失也较低。蜂窝结构体是具有多孔质的隔壁和位于最外周的外周壁的柱状的蜂窝结构体，该多孔质的隔壁区划形成多个隔室，该多个隔室形成流体的流路，并从流体的流入侧的端面即流入端面延伸至流体的流出侧的端面即流出端面，其中，在隔壁的表面的至少一部分具有表面层，表面层包含磁性体粒子且具有通气性。
