The electrically heated catalyst (1) has a honeycomb substrate (2), an electrode (3) and a joint (4). The honeycomb substrate (2) and the bonding portion (4) contain the matrices (201), (401) and the conductive fillers (202), (402). The matrix (201) (401) contains a borosilicate containing at least one of an alkali metal atom and an alkaline earth metal atom. The softening point of the bonding portion (4) is preferably lower than that of the honeycomb substrate (2). |
