ABSTRACT:
A liquid jet recording head is provided with a liquid discharging portion having an orifice for discharging liquid and forming flying liquid droplets, and a liquid flow path communicating with the orifice and having as a part of the construction thereof a heat-acting portion in which heat energy generated in a heat-generating portion for forming the liquid droplets acts on the liquid, and an electro-thermal converting element electrically connected to a heat-generating resistive material layer provided on a base plate, the electro-thermal converting element having at least a pair of opposed electrode wiring portions provided on the heat-generating resistance material layer, the heat-generating portion being formed between the electrode wiring portions. The width of the heat-generating resistive material layer in at least the part of the heat-generating resistive material layer in the area in which the electrode wiring portions are layered is greater than the width of the electrode wiring portions.
