摘要：
A printing head includes a printing element substrate that is hard to be deformed even if the printing head falls by mistake. The printing head comprises element substrate in which an energy generating element for generating energy used for ejecting ink is provided, a first sheet-shaped portion to which the element substrate is provided, a second sheet-shaped portion provided away from the first sheet-shaped portion at an opposite side to a direction of ejecting the ink in relation to the first sheet-shaped portion, and a sheet-shaped wall member connecting the first sheet-shaped portion to the second sheet-shaped portion, wherein the wall member has a thickness of a portion connected to the second sheet-shaped portion, which is larger than a thickness of a portion connected to the first sheet-shaped portion.
