ABSTRACT:
There is provided a cell structure, where the outer wall portion has high heat-insulating ability, the cell structural portion has a high temperature rise rate, and a temperature distribution is more uniform, and a method for manufacturing the cell structure. The cell structure1includes: a cell structural portion4having partition walls forming a plurality of cells extending from one end face to the other end face, and an outer wall portion5disposed on an outer peripheral surface of the cell structural portion4.The outer wall portion5has at least a porous layer having a porosity of 40% or more or a porous layer having a hollow body. The manufacturing method can easily manufacture the cell structure.
