The present invention provides a bump-joining apparatus, a bump-joining method, and a semiconductor component-manufacturing apparatus whereby bumps and electrode portions of circuit board are perfectly joined with higher join strength than in the conventional art. The apparatus includes a vibration generation device, a pressing device and a control unit, wherein bumps are pressed to electrode portions of a circuit board and vibrated with ultrasonic waves after reaching an initial contact area before reaching a join-completed-contact area at a completion of the joining, so that the bumps are more perfectly joined to the electrode portion than in the conventional art which vibrates the bump only after reaching the join-completed-contact area. Larger join strength is achieved than in the conventional art.
