摘要：
A liquid jet recording head having a support member, an electrothermal converting body on the support member, the converting body including a heat generating resistor layer and electrodes electrically connected to the layer, and an upper protective layer over the converting body containing a ion exchanger. The ion exchanger functions to trap mobile ions permeating from the liquid flowing through the recording head thereby preventing corrosion.
