PROBLEM TO BE SOLVED: To permit the further enlargement of a merit due to employing two kinds of liquid by a method wherein liquid, supplied into a foaming area, and the other liquid, not passing through the foaming area, are not provided with compatibility to ensure the separating condition of these kinds of liquid in a head. SOLUTION: In a liquid discharging head, in which bubbles are guided to the side of a discharging port by a movable member, a first liquid and second liquid are specified so as not to have compatibility. In the liquid discharging head, a second flow passage 16 of liquid for foaming is located above an element substrate 1 provided with a heat generating body 2 for giving heat energy for generating bubbles to liquid while a first flow passage 14, communicated directly with the discharging port 18, is arranged above the second flow passage. The upstream side of the first liquid flow passage is communicated with a first common liquid chamber 15 for supplying the discharging liquid to a plurality of first liquid flow passages while the upstream side of the second liquid flow passage is communicated with a second common liquid chamber for supplying the liquid into a plurality of second liquid flow passages. |
