Abstract
A liquid jet recording head is provided with a liquid discharging portion having an orifice provided to discharge liquid and form 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 for forming the liquid droplets acts on the liquid. The heat acting portion includes electro-thermal converting element comprising a heat-generating resistive layer provided on a base plate and at least a pair of opposed electrodes between which a heat-generating portion is formed by the resistive layer, wherein the width of the electrodes in at least the portion thereof which is in contact with the heat-generating portion is greater than the width of the heat-generating resistive layer corresponding thereto.
