Document Type and Number:
WIPO Patent Application WO/2007/122779
Kind Code:
A1
Abstract:
A honeycomb structure that is free from misalignment in the positional relationship
between individual through-holes of each laminate member after lamination,
being reduced in pressure loss and being free from cell clogging. There is provided
a columnar honeycomb structure having a laminate member with multiple through-holes
laminated so as to form multiple cells, characterized in that the laminate member
has nearly a disk shape, and that a positioning structure, such as a planar portion
or projecting portion, is disposed on the outer circumference side face of the
laminate member. Further, there is provided a columnar honeycomb structure
having a laminate member with multiple through-holes laminated so as to form
multiple cells, wherein the laminate member has a configuration of disk split
into multiplicity so that a disk configuration as a whole is created by combining
of pieces of split configuration.
