Liquid jet recording head

摘要

A liquid jet recording head comprises an orifice for forming flying liquid droplets by ejecting liquid, a heat actuating portion communicated with the orifice and where thermal energy for forming liquid droplets is applied to the liquid, at least one pair of electrodes electrically connected with a resistive heater layer provided on a support, an electrothermal transducer disposed between said one pair of electrodes and constituting a heat generating portion, at least one part of said one pair of electrodes disposed opposite each other sandwiching an insulating layer, characterized in that at least one electrode of said one pair of electrodes and said insulating layer are not disposed under the heat generating portion.
