Abstract
A liquid supply mechanism includes a tank configured to store liquid, a supply passage having an end connected to the tank so as to allow the liquid to flow, and an ejection member disposed on the supply passage so as to eject the liquid. The ejection member includes a filter, a check valve, and an ejection passage. The filter has a predetermined passage resistance to the passing liquid. The check valve is opened at a predetermined opening pressure for the passing liquid. The ejection passage allows the liquid to flow when the check valve is opened and ejects the liquid from an ejection port formed at a tip thereof. A pressure decompressed by the passage resistance of the filter is larger than the opening pressure of the check valve.
