Abstract
An ultrasonic welding structure is provided for a chip body,and a lid body,to be welded to each other by using ultrasonic waves. The chip body,is provided with a welding recess,defined by tapered sidewalls,A,,A. While, the lid body,is provided with a welding projection,also defined by tapered sidewalls,C,,C, for engagement with the welding recess,. The chip body,and the lid body,in their assembled condition are subjected to ultrasonic oscillation characterized by its amplitude direction A. Then, since the welding surfaces of the sidewalls,A,,C each has a projected area with respect to the amplitude direction A, the welding surfaces are welded to each other owing to frictional heat resulting from the ultrasonic oscillation. With this welding structure, the chip body,is perfectly welded to the lid body,by one time of ultrasonic oscillation.
