<p>A liquid jet recording head comprises a substrate (103) having a support; and an electricity-heat converter (107) arranged on the support, having a heat-generating resistor layer and a pair of electrodes (105, 106) electrically connected to the heat-generating resistor, with a heat-generating portion being formed between the pair of electrodes; where DELTA T = TH - To being 20 DEG C or more and 100 DEG C or less; and a member provided on the substrate for forming the liquid channel for the liquid for recording (To is the peak value of the temperature of the electricity-heat converter under driven state when no liquid for recording exists at the position of the surface of the substrate corresponding to the heat-generating portion on the surface where the bubble generated in the liquid for recording disappears; and TH is the peak value of the temperature of the electricity-heat converter under driven state when no liquid for recording exists at other positions than the above position).</p> |
