PROBLEM TO BE SOLVED: To provide an ultrasonic bonded structure capable of preventing a joined portion of two plate members from being broken even when the structure is subjected to the vibration. SOLUTION: In the ultrasonic bonded structure for performing the ultrasonic bonding by overlapping bonding surfaces of two plate members each other, and giving the ultrasonic vibration while applying the pressure thereto, stress absorption portions 70 capable of absorbing the stresses exerted in a bonded part 71 are formed separately on the proximal side of the bonded part of one plate member.
