Abstract
A honeycomb structure () having a large number of through-holes () formed in the axial direction and defined by partition walls, wherein slits () are formed so as to be exposed to at least part of the outer surface () of the honeycomb structure along the axial direction. In this honeycomb structure, each portion can deform freely without being restricted by other portion even when an uneven temperature distribution appears therein; as a result, reduction in thermal stress is possible and generation of cracks can be prevented.
