a base;

a plurality of heaters, each of which is provided in a layer on the base and configured to generate heat for discharging ink;

a flow path member that, forms an ink flow path and is configured to form, together with the base, a bubbling chamber having a heater in a bottom surface thereof in which the ink can be bubbled by heat of the heater provided therein; and

a plurality of temperature sensors, each of which is capable of detecting a temperature of the bubbling chamber, each of the temperature sensors being formed of the same material as the plurality of heaters and being provided on the base in the same layer as the plurality of heaters, wherein

a heat dissipation pattern overlaps the heaters in a planar view, the heat dissipation pattern being formed in a lower layer with respect to the heaters and being connected to the base via a conductive plug,

at least one temperature sensor is provided for each heater, and

each temperature sensor overlaps the bubbling chamber in a planar view.
