In a method of mounting an electronic component on a substrate, electrode terminals on at least one of the substrate and the electronic component are composed of solder bumps. The electrode terminals of the substrate and the electrode terminals of the electronic component are placed in contact and ultrasonic vibration is applied to at least one of the substrate and the electronic component to provisionally bond the electrode terminals together. A gap between the substrate and the electronic component is then filled with flux fill, and the electrode terminals of the substrate and the electronic component are bonded by reflowing the solder bumps.
