Abstract
A liquid jet type recording head comprises a liquid discharge section including an orifice for discharging the liquid to form flying droplets and a liquid passage providing part of a heat acting portion at which thermal energy acts on the liquid to form droplets, at least a pair of opposed electrodes electrically connected with a heat generating resistive layer on a substrate, and an electro-thermal converting element having a heat generating portion located between the electrodes, in which at least one of the electrodes is a turned electrode in which at least a portion thereof adjacent to said heat generating portion has a width smaller than that of said heat generating portion.
