A liquid introduction member includes an inlet into which a liquid is introduced, a filter to filter the liquid introduced from the inlet, a filter chamber in which cross-sectional areas of the flow path increase from the inlet side to the filter side, and a supply flow path to supply the liquid that has passed through the filter to the nozzle side. The filter chamber has at least one guide extending from an inner wall surface of the filter chamber toward the inlet with a space between the guide and the filter, a bottom surface of the guide has a guide surface to guide bubbles which have entered from the inlet, and the guide guides the bubbles into the space by use of the guide surface to spread the bubbles onto the filter toward an outer periphery of the filter.
