一体的に固相拡散接合することを特徴とする。In order to achieve the above object, an ultrasonic bonding method according to the present invention comprises applying an ultrasonic wave to a metal foil laminated on a metal member and applying ultrasonic waves to the metal foil. In the ultrasonic bonding method of solid-phase diffusion bonding of the metal foil to the metal member, a metal plate is placed on a bonding position of the metal foil, and ultrasonic waves are applied through the metal plate to form the metal foil and When the metal plate is integrally solid-phase diffusion bonded to the metal member, one end of the metal plate is placed on a bonding position of the metal foil and the other end is mounted on the metal foil.

するものと考えられる。In general, in the ultrasonic bonding method, by applying ultrasonic vibration to the superposed metal materials, the metal in the portion where the ultrasonic vibration has acted vibrates, and the metal materials are mutually solid-phase diffusion bonded. However, the action of the ultrasonic vibration is strongest in the portion where the ultrasonic horn is in contact, and the diffusion amount of the metal is large in this portion. As a result, the strength of the metal structure is reduced around the portion where the ultrasonic horn is in contact, and in an extremely thin material such as a metal foil, a crack is generated from this portion when stress concentration occurs. Conceivable.

Ultrasonic vibration is applied to the metal foil which prevents vibration from acting and which is sufficient for the metal foil to be solid-phase diffusion bonded and bonded to another metal material. Therefore, the metal foil is solid-phase diffusion bonded to the metal member together with the metal plate,
In addition, sufficient bonding strength can be obtained.

Moreover, by applying ultrasonic waves through the end of the metal plate placed on the joining position of the metal foil, excessive ultrasonic vibration is applied to the metal foil as in the above-described embodiment. In addition, it is possible to obtain an effect that the ultrasonic vibration is applied to the metal foil enough to prevent the metal foil from being fused and to be bonded to the metal plate and the metal member by fusing the metal foil.

And the end 3a of the aluminum plate 3
The ultrasonic wave is applied through the end 3a of the aluminum plate 3 by scanning an aluminum horn 2 in the width direction by contacting an ultrasonic horn (not shown). As a result, a joining portion 4 is formed at the joining position as shown by the imaginary line in FIG. 1, and the aluminum foil 2 and the aluminum plate material 3 are

2の端部を包み込むことが困難になることがある。The aluminum plate member 3 can prevent an excessive ultrasonic vibration from acting on the adjacent uppermost aluminum foil 2, and can prevent the aluminum foil 2 and the aluminum member 1 from being excessively vibrated.
Any thickness can be used as long as it can apply ultrasonic vibrations that can vibrate and solid-phase diffusion bonding can be performed integrally with each other, and the thickness is not particularly limited. In joining, it is preferable to have a thickness in the range of 0.05 to 1.0 mm. Aluminum plate 3
Is thinner than the aluminum foil 2 and less than 0.05 mm, it is easily broken and handling becomes difficult. When the thickness of the aluminum plate 3 exceeds 1.0 mm, the output of the ultrasonic wave must be increased in order to integrally solid-phase diffusion-bond the aluminum foil 2 and the aluminum member 1 to each other. However, an increase in manufacturing costs is inevitable. Also,
More preferably, the aluminum plate 3 has a thickness in the range of 0.1 to 0.5 mm. When the thickness of the aluminum plate 3 is less than 0.1 mm, the effect of protecting the aluminum foil 2 may not be sufficiently obtained,
If the thickness of the aluminum plate 3 exceeds 0.5 mm, the strength of the aluminum plate 3 itself increases, and it may be difficult to wrap the end of the aluminum foil 2.
