Abstract: A support for an electric heating type catalyst includes: a honeycomb structure having: porous partition walls extending through the honeycomb structure from an inflow end face to an outflow end face to define a plurality of cells forming a through channel; and an outer peripheral wall located at the outermost periphery; a pair of electrode layers disposed on the outer peripheral wall of the honeycomb structure; and a pair of electrode portions. Each of the electrode layers is formed in a strip shape extending in an extending direction of the cell of the honeycomb structure. In a cross section orthogonal to the extending direction of the cell, one electrode layer of the pair of electrode layers is disposed on a side opposite to the other electrode layer across a center of the honeycomb structure. Each of the electrode layers is electrically connected to each of the electrode portions via two or more base layers, and the base layers have conductivity and are spaced apart from each other. Each of the electrode portions includes two or more electrodes, and each of the electrodes is fixed to outer surfaces of the base layers.

Abstract: A method for measuring a heat generation distribution in a honeycomb structure includes: applying a voltage to a pair of electrode layers of the honeycomb structure to bring the honeycomb structure to an electrically conductive state; measuring resistance values Rn between two different points on the surface of an outer peripheral wall of the honeycomb structure; estimating a current value In flowing between the two points using Kirchhoffs law based on each of the resistance values Rn between the two different points, and calculating a heat value generated for each of the resistance values Rn based on each of the resistance values Rn and the current value In; and estimating a heat generation distribution in the honeycomb structure based on both the positions at which each of the resistance values Rn is measured, and the heat value calculated from each of the resistance values Rn, in the honeycomb structure.
