发明名称 DROPLET DISCHARGE HEAD AND IMAGE FORMING APPARATUS
摘要 PROBLEM TO BE SOLVED: To improve flatness of a surface of a substrate to improve reliability in joint.SOLUTION: Both ends of a common liquid chamber extending along a direction in which nozzle holes are arranged are narrowed down, and at a part of a resin board material between both ends of a common liquid chamber in the adjacent column, an opening 23-2b of a notch formed by removing a part of a resin material at the part is provided. As a result, thickness of a space part of an injection molding mold forming a part sandwiched between the opposite ends of the adjacent common liquid chambers becomes roughly the same as thickness of a space part of an injection molding mold forming the center part in a longitudinal direction of the adjacent common liquid chambers.
