Abstract:
A method for manufacturing a flow passage assembly includes forming a first flow passage in a first joint interface formed by welding a first surface of a first flow passage forming member to a first surface of a second flow passage forming member using an ultrasonic welding process, and forming, after the first flow passage is formed, a second flow passage in a second joint interface formed by welding a first surface of a third flow passage forming member to one of a second surface of the first flow passage forming member and a second surface of the second flow passage forming member using an ultrasonic welding process. A total area of weld portions used when the first flow passage is formed is greater than a total area of weld portions used when the second flow passage is formed.
