<P>PROBLEM TO BE SOLVED: To increase the strength of a joined part of a work after the ultrasonic bonding is completed. <P>SOLUTION: An ultrasonic bonding equipment has an anvil 110 and a horn 140 arranged facing the anvil, and performs the ultrasonic bonding of the work to be bonded by pressurizing and oscillating electrode tabs 210 as a plurality of works overlapped and set on the anvil by the horn. Gripping force on the outer side part is set to be smaller than the gripping force on the inner side part in a gripping area to the works by the anvil and the horn. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
