Abstract
An electrically heated catalyst device includes a catalyst support, a low-potential-side electrode, and a high-potential-side electrode. In a case in which a current value between two electrodes, which are the low-potential-side electrode and the high-potential-side electrode, is gradually increased from 0, the current value between the two electrodes is referred to as an electrode fusing current value when, in each of the low-potential-side electrode and the high-potential-side electrode, a temperature of any section of the electrode first reaches a melting point of a material of the electrode. The low-potential-side electrode is configured to have a lower electrode fusing current value than the high-potential-side electrode.
