The processor is configured to start the supply of power to the heater at a predetermined timing before a starter for cranking the internal combustion engine is turned on and increase power supplied to the heater when the starter is turned on.

Control device of exhaust sensor

A gas sensor element has an electrolyte layer, a first insulator, a second insulator, a measurement gas chamber, and a reference gas chamber. The electrolyte layer includes a holding plate and a solid electrolyte body. The first insulator is laminated on one side of the electrolyte layer, and the second insulator is laminated on the other side of the electrolyte layer. At least a part of the boundary portion between the placement hole and the solid electrolyte body is sandwiched between a first sandwiching portion of the first insulator and a second sandwiching portion of the second insulator.
