    • A primary flow path forming member is provided with a groove which becomes a recording liquid supply path on a bottom surface thereof. A second flow path forming member is provided with an arm portion. The arm portion of the second flow path forming member is used as a cap for closing the opening of the groove which becomes the liquid supply path formed on the bottom surface of the prime flow path forming member. The primary flow path forming member and the second flow path forming member as described above are formed by injection-molding and bonded with each other by a bonding member. The bonding member is formed to cover a portion where the opening edge of the groove which becomes the recording liquid supply path, in the primary flow path forming member abuts on the arm portion of the second flow path forming member.
    • 主流路形成构件在其底面设置有成为记录液供给路的槽。 第二流路形成构件设置有臂部。 第二流路形成构件的臂部用作封闭形成在主流路形成构件的底面上的液体供给路径的槽的开口的盖。 如上所述的主流路形成部件和第二流路形成部件通过注射成型而通过接合部件彼此接合而形成。 接合部件形成为覆盖在一次流路形成部件中成为记录液供给路的槽的开口边缘与第二流路形成部件的臂部抵接的部分。

    • An inkjet recording head includes a recording-element substrate having arranged therein multiple sets of nozzles that discharge ink, energy-generating elements that generate energy used for discharging the ink, and supply ports that supply the ink to the nozzles; and a sealant disposed around the recording-element substrate. The supply ports include a first supply port disposed near a first edge of the recording-element substrate and a second supply port disposed near a second edge of the recording-element substrate, the second edge being opposite to the first edge as viewed in the arrangement direction of the multiple sets. As viewed in the arrangement direction, a distance between the second edge and the second supply port is shorter than a distance between the first edge and the first supply port, and a volume of the sealant near the second edge is smaller than a volume of the sealant near the first edge.
    • 喷墨记录头包括记录元件基板,其中布置有多组排出墨水的喷嘴,产生用于排出墨水的能量的能量产生元件,以及向喷嘴供应墨水的供给口; 以及设置在记录元件基板周围的密封剂。 供给端口包括设置在记录元件基板的第一边缘附近的第一供给口和设置在记录元件基板的第二边缘附近的第二供给口,第二边缘与第一边缘相对,如图所示 方向多套。 从排列方向观察,第二边缘和第二供给口之间的距离比第一边缘和第一供应口之间的距离短,并且第二边缘附近的密封剂的体积小于 密封胶靠近第一边。
