ABSTRACT:
A liquid jet recording head comprises a substrate having a resistive heater layer and at least one pair of mutually confronting electrodes electrically connected with the resistive heater layer at least one part of each of said one pair of electrodes being coated with the resistive heater layer.
A liquid jet recording head comprises a support, an electrothermal transducer provided on the support which is composed of at least a resistive heater layer and one pair of electrodes mutually confronting and electrically connected with the resistive heater layer, and a liquid flow path constructing member provided in correspondence with the electrothermal transducer and constituting a liquid flow path communicating with an orifice for ejecting liquid. The electrodes and the resistive heater layer are formed successively on the support to form the electrothermal transducer.
