In this way, the distance from the first heater first terminal and the first heater second terminal to the first notch becomes short, so that the interference between the first lead wire and the second lead wire and the first baffle is avoided. While these leads are easy to route. Further, since the distance from the second heater first terminal and second heater second terminal to the second notch is shortened, interference between the third lead wire and the fourth lead wire and the second baffle is avoided, It is easy to route the lead wire.
