Liquid discharge head and manufacturing method of the same
Abstract:
A liquid discharge head includes a discharge port member including a discharge port, a flow path member including a pressure chamber and a liquid flow path, a substrate, and a structure that is arranged on the substrate on an upstream side of a center of the discharge port and that is configured to generate a flow of the liquid toward the discharge port. The liquid in the pressure chamber circulates. A position corresponding to a portion of the structure having a greatest height from a surface of the substrate is located on the upstream side of the center of the discharge port in a flow direction of the liquid. A thickness of the structure in a discharge direction of the liquid is 0.1 times or greater than a thickness of the liquid flow path in the discharge direction of the liquid.
