    • A liquid ejecting head includes a fixing plate which includes a bottom surface which is fixed onto the nozzle surface of each of a plurality of head units which are provided to line up in a state in which a first gap is formed along a first direction, and a first side surface which extends from an edge of the bottom surface which is positioned closer to an outside in the first direction than the lined-up head units to the head unit side. The fixing plate includes a second gap which is formed between the first side surface and the head units which are positioned at ends in the first direction among the head units. The liquid ejecting head also includes a second outer circumferential mold which fills at least a portion of the first gap, and a third outer circumferential mold which fills at least a portion of the second gap. The third outer circumferential mold fills the second gap at a position which is distanced further from the bottom surface than the second outer circumferential mold in a direction which is perpendicular to the bottom surface, and a hardness of the third outer circumferential mold is higher than a hardness of the second outer circumferential mold.
    • 液体喷射头包括固定板,该固定板包括固定在沿着第一方向形成有第一间隙的状态下设置为排列的多个喷头单元的喷嘴表面上的底表面,以及 所述第一侧表面从所述底表面的边缘朝向所述头单元侧在所述第一方向上比所述排列头单元更靠近外侧延伸。 所述固定板包括形成在所述第一侧表面和所述头单元之间的第二间隙,所述第一间隙位于所述头单元中沿所述第一方向的端部。 液体喷射头还包括填充第一间隙的至少一部分的第二外周模具和填充第二间隙的至少一部分的第三外周模具。 第三外周模具在垂直于底面的方向上在比第二外周模具更远离底面的位置处填充第二间隙,并且第三外周模具的硬度高于 第二外周模具的硬度。
