<p>A substrate containing silicon is coated with primer containing silane coupling agent. A hard resin product is brought into contact with the primer coated part of the substrate and the resin product is vibrated while the product is pressed to the substrate. A welding apparatus has a welding gun having a horn which holds the resin product, a holding table which is placed movably beneath the horn and holds the substrate between the horn and itself, a transfer means which transfers the welding gun and the holding table relatively to each other and a converter which generates ultrasonic vibration of the horn in accordance with inputted signals. Thus, a resin product is welded to a substrate firmly at a low cost.</p> |
