    • A liquid ejecting head includes a flow path formation substrate on which individual flow paths communicating with nozzle openings for ejecting liquid are provided, a first member which is provided at one surface side of the flow path formation substrate and has pressure generation units for generating pressure change in liquid in the individual flow paths, and a second member which is provided at a surface side of the flow path formation substrate, which is opposite to the first member. Dummy flow paths are provided on the flow path formation substrate independently of the individual flow paths. Exposure portions which expose a part of wall surfaces of the flow path formation substrate which form the dummy flow paths, are provided at least one of the first member and the second member.
    • 液体喷射头包括:流路形成基板,其上设置有与用于喷射液体的喷嘴开口连通的各个流路;第一部件,设置在流路形成基板的一个表面侧,并具有用于产生压力变化的压力产生单元 以及设置在与第一部件相反的流路形成基板的表面侧的第二部件。 独立于各个流动路径,在流路形成衬底上提供虚拟流动路径。 设置有形成虚拟流路的流路形成基板的一部分壁面的曝光部,设置在第一部件和第二部件中的至少一个上。
