Abstract
A honeycomb body of a honeycomb structure is made of ceramic, and a plurality of electrodes are provided apart from one another on a surface of the honeycomb body. In the honeycomb body, energization is performed for each of a plurality of current paths Xa to Xc formed by the plurality of electrodes, thereby heating the honeycomb body. A controlling device detects heater current Ia, Ib, and IC that flow when a predetermined voltage is applied for each of the plurality of current paths Xa, Xb, and Xc, and controls an energization timing of each current path Xa to Xc based on the detection results.
