    • An ink jet head includes a substrate provided with heat generating members for generating a bubble in ink on a surface of the substrate, a plurality of discharge ports for discharging the ink, the ports opposed to the surface of the substrate, and a plurality of ink flow passages communicating with the plurality of discharge ports to feed the ink. A plurality of the heat generating members is provided in each of the ink flow passages, and the discharge port is arranged on an extension line extending from a center of a pressure generating area composed of the plurality of heat generating members toward the surface of the substrate in a normal direction. Moreover, a distance dhc between centers of each of two heat generating members arranged most apart from each other among the plurality of heat generating members is set to be larger than a diameter do of an aperture of the discharge port. In the ink jet head, even if the center position of the discharge port and the center position of the pressure generating area are somewhat shifted from each other, main liquid droplets of the ink are discharged from the discharge port without generating no shift in their discharge directions.
    • 喷墨头包括:基板,其设置有用于在基板的表面上产生油墨的发热部件,用于排出墨水的多个排出口,与基板的表面相对的端口,以及多个墨水 与多个排出口连通的流动通道供给油墨。 在每个墨流动通道中设置有多个发热元件,并且排出口设置在从由多个发热元件组成的压力产生区域的中心朝向基板的表面延伸的延伸线 在正常的方向。 此外,将多个发热部件中彼此最大配置的两个发热部件的中心之间的距离dhc设定为大于排出口的孔径的直径do。 在喷墨头中,即使排出口的中心位置和压力​​产生区域的中心位置相互稍微偏移,墨水的主液滴从排出口排出,也不会产生排出位移 方向。
