Title:
A honeycomb structural body and a manufacturing method for the same
Document Type and Number:
Japanese Patent JP6038711
Kind Code:
B2
Abstract:
There is disclosed a honeycomb structure which is a catalyst carrier and also functions as a heater when a voltage is applied thereto and which can inhibit an unevenness of a temperature distribution when the voltage is applied thereto. A honeycomb structure 100 includes a tubular honeycomb structure body 4 having porous partition walls 1 to define and form a plurality of cells 2 and an outer peripheral wall 3, and a pair of electrodes 21 disposed on a side surface 5 of the honeycomb structure body 4. An electrical resistivity of the honeycomb structure body 4 is from 1 to 200 ©cm, each of the pair of electrodes 21 is formed into a band-like shape extending in an extending direction of the cells 2 of the honeycomb structure body 4, one electrode 21 in the pair of electrodes 21 is disposed on a side opposite to the other electrode 21 in the pair of electrodes 21 via a center of the honeycomb structure body 4, the honeycomb structure body 4 is constituted of an outer peripheral region 6 and a central region 7, and an electrical resistivity of a material constituting the outer peripheral region 7 is lower than an electrical resistivity of a material constituting the central region 6.
