The plurality of discharge ports have regions where the angles of contact with the liquid are different around the discharge ports, and the regions in the discharge ports where the contact angles are relatively small are formed at different positions in the plurality of discharge ports, and the liquids discharged from the plurality of discharge ports are discharged in directions away from each other.
