HONEYCOMB STRUCTURE

摘要

A honeycomb structure includes a plurality of honeycomb segments partitioned by partition walls and having a plurality of circulation holes penetrating in one axial direction; and a bonding layer existing between the adjacent honeycomb segments for bonding the plurality of honeycomb segments. The bonding layer is formed by use of a bonding material including oxide fibers which satisfy the following relational expression. 0.5≤L x (W / D) / 100≤8 L is an average length ( mu m) of the oxide fibers in a longitudinal direction, D is specific gravity (g/cm<3>) of the oxide fibers, and W is mass percentage of content (% by mass) of the oxide fibers in the entire bonding material.
