Abstract: In ultrasonic bonding of a metal terminal to a substrate pad, a thin buffer metal layer which is formed of a soft metal or a highly slidable metal is interposed between a terminal edge and a pad so as to prevent direct contact between an end of the terminal and the pad upon bonding. This makes it possible to prevent abrasion and a crack in the pad at the end of the terminal caused by pressure and an ultrasonic wave upon the ultrasonic bonding. This makes it possible to realize a compact bonded structure with high reliability.
