摘要：
In a process for manufacturing an electrothermal transducer for a liquid jet recording head comprising a support, a resistive heater layer overlying the support, at least a pair of electrodes electrically connected with the resistive heater layer and disposed opposite to each other, and a protective layer composed of an insulating material, at least defective portions in the protective layer of the electrothermal transducer are subjected to an anodic oxidation treatment.
