Abstract:
A liquid discharge recording head includes a substrate having a liquid supply opening facilitating supplying liquid and heating resistors for generating energy for discharging the liquid, a flow path member having discharge openings and flow paths including first and second flow paths that are adjacent each other, the second flow path being longer than the first flow path, and a first resister corresponding to the first flow path and a second resistor corresponding to the second flow path, each of the first and second resistors being disposed at an area of the flow path member which is situated in correspondence with the liquid supply opening, wherein an amount of protrusion of the first resister at a side of the first flow path is greater than an amount of protrusion of the second resister at a side of the second flow path.
