PROBLEM TO BE SOLVED: To provide a method of bonding an optical package to a lens which can easily and accurately adjust a distance between the optical package and the lens, and the optical package.SOLUTION: A thermoplastic resin 30 is used to bond a condensing lens 20 to the optical package 1 containing an optical element 3 for integration. First, the thermoplastic resin 30 is disposed between bonding surfaces 4 and 21 of the optical package 1 and the lens 20 to align the optical element 3 with a light axis X of the lens 20 while they are in contact with each other. Then, the thermoplastic resin 30 is heated by a heater 40 to be melted. In addition, a distance between the bonding surfaces 4 and 21 is controlled while applying pressure to the lens 20 toward the optical package 1, and an excess of the thermoplastic resin 30 is discharged together with air bubbles from between the bonding surfaces 4 and 21. By the molding of the thermoplastic resin 30 to a joint 30a, the optical package 1 and the lens 20 are bonded. |
