A liquid jet recording head for discharging liquid droplets onto a recording medium includes a support, heat-generating resistance layer provided on the support for generating heat energy to discharge the liquid droplets, a pair of electrodes electrically connected to the heat-generating resistance layer, and heat-generating sections each serving as a portion for generating the heat energy, each head generating section comprising the heat-generating resistance layer sandwiched by the pair of electrodes. Plural discharge openings serve to discharge liquid droplets, a liquid chamber houses liquid, and there are plural liquid paths, each liquid path having an associated heat generating section, and communicating with an associated discharge opening and with the liquid chamber to supply liquid to the associated discharge opening from the liquid chamber. An layer on the support protects the heat-generating resistance layer and pair of electrodes, and the upper layer has an organic resin layer of organic material, and this organic resin layer is formed only on a whole region upstream of the heat-generating sections on the support in a liquid supply direction.
