摘要： The portions at the circumferential edges of a flow channel formation plate in which the corner portions of a dummy flow channel portion are formed are weaker than other portions, and thus when thermal stress has occurred due to temperature changes when the constituent elements of a flow channel unit are affixed to each other, cracks can be induced preferentially in the weak portion, rather than the other portions, starting from the ends of the corner portions. In particular, although similar corner portions are formed in a common liquid chamber, the intersection angle of the corner portions in the dummy flow channel portion is smaller than the intersection angle of the corner portions in the common liquid chamber, and thus it is easier for stress to concentrate in the corner portions of the dummy flow channel portion.
摘要翻译：形成虚拟流路部的角部的流路形成板的周缘部的部分比其他部分弱，因此当流路的构成要素发生热应力时，由于温度变化单元彼此固定，从拐角部分的端部开始，优先在弱部而不是其它部分引起裂纹。特别地，虽然在公共液体室中形成相似的角部，但是虚设流路部中的角部的交叉角度小于公共液体室的角部的交叉角度，因此更容易应力集中在虚拟流路部分的角部。
