    • An ink jet head includes a substrate having a flow path construction member constructing a plurality of discharge ports for discharging ink and a plurality of ink flow paths corresponding thereto, and a plurality of energy generating elements corresponding to the plurality of discharge ports. The substrate has an ink supply port for supplying ink to the ink flow paths. The ink supply port includes a first liquid chamber disposed on a plane on which the energy generating elements are formed, and having a grooves with island-shaped columns left, and a second liquid chamber disposed on the opposed plane, and having a plurality of through holes partitioned at positions corresponding to the island-shaped columns. In the ink jet head, the island-shaped columns and a partition wall for the through holes are left as a beam construction section, thereby improving a mechanical strength of a semiconductor substrate. Also, the first liquid chamber has a groove with island-shaped columns left, thereby enabling ink to be adequately supplied from the ink supply port to the discharge ports.
    • 喷墨头包括具有构造用于排出墨的多个排出口和与其对应的多个墨水流路的流路构造构件的基板和与多个排出口对应的多个能量产生元件。 基板具有用于向油墨流路供给油墨的供墨口。 供墨口包括设置在其上形成有能量产生元件的平面上的第一液体室,并且具有留下岛状柱的槽和设置在相对平面上的第二液体室,并且具有多个通孔 在与岛状列相对应的位置处划分的孔。 在喷墨头中,岛形柱和用于通孔的分隔壁被留作为梁结构部分,从而提高半导体基板的机械强度。 此外,第一液体室具有留下岛状柱的凹槽,从而使得墨水能够从供墨口适当地供应到排出口。
