摘要：
In the case where a lens unit where two ore more transparent resin lenses are combined is constituted, at least one transparent resin lens contains infrared absorbent. When the lens unit is assembled, an infrared laser is emitted to a joined portion between the transparent resin lens and the other transparent resin lens. As a result, the emitted infrared ray is absorbed by the infrared absorbent, so that the transparent resin lenses are welded to each other. An opaque lens barrel which holds the entire lens unit and the transparent resin lenses are joined by welding.
