In a manufacturing method of a composite product, a first resin part and a second resin part are prepared. The first resin part has an opening of which inner diameter decreases in an axial direction thereof. The second resin part is inserted into the opening of the first resin part. An outer surface of the second resin part is pressed to an inner surface of the opening of the first resin part. Then a laser beam is radiated to a contacting area between the outer surface of second resin part and the inner surface of first resin part, with pressing the outer surface to the inner surface. |
