Abstract
In a circulation channel, which is configured at least with an ejection unit, a first pressure adjusting unit, a second pressure adjusting unit, a pump, and a temperature adjusting unit, liquid supplied from the outside flows into the first pressure adjusting unit and then flows out of the first pressure adjusting unit into the ejection unit and the second pressure adjusting unit. The liquid that has flowed out of the ejection unit and the liquid that has flowed out of the first pressure adjusting unit flow into the second pressure adjusting unit and then flow out of the second pressure adjusting unit into the pump. The pump sends the liquid that has flowed out of the second pressure adjusting unit to the first pressure adjusting unit, and the temperature of the circulating liquid is adjusted by the temperature adjusting unit.
