PURPOSE:A liquid jet recording head free from defect in connecting parts due to a shift in etching an electrode part, by enlarging the width of the electrode part adjacent to the boundary of a heating part, in providing an electrode part at an end of a heating part on a substrate. CONSTITUTION:When providing the electrode part by a photo-etching method on the heating part provided on the substrate, the width W2 of the part of the electrode part connected to the heating part is set to be large, whereby the connection width is made to be constantly fixed even when there is some shift in the position of the electrode part, and unrequired generation of heat by the heating part is obviated. Accordingly, any defect due to a shift in photo-etching the electrode part is completely prevented from occurring.
