Abstract

PURPOSE:To provide the subject head wel adapted for a multihead having a number of piezo elements and excellent in connecting strength, long-duration reliability and mass-productivity by connecting the electrodes of piezo elements to voltage applying lead terminals by a gang bonding method. CONSTITUTION:A piezo element 6 having lower and upper electrodes 7 and 8 is provided on the outer wall surface of the pressure chamber 2 of an on-demand type ink jet recording head 13, and on the electrodes 7 and 8 there are applied metal bumps 18 each havin a diameter of about 100mum and a height of from 20 to 30mum. On the other hand, the end parts of lead terminals 14 and 15 constituted by copper foils 17 laminated on the insulating base plates 16 are formed by a copper foil single body, the end part of the copper foil being plated with gold and tin plating being applied thereon. The end parts of the terminals 14 and 15 are superimposed on the gold bumps 18, and are heated and pressed thereby to connect tin on the copper foil to gold of the gold bump 18 as an eutectic alloy.
