To provide a laminated bar-like lamp device and its manufacturing method.
Utilizing a laminated layer unit composed of a lower laminated layer and an upper laminated layer in which wide variety of holding holes can be formed, a conductive unit is laminated between the laminated layer unit by a band-shaped production method, exposing the conductive unit only from the holding hole parts, to cover and fix the conductive unit. Using the holding holes, light source units are conjoined and worked by a subordinate conjoining method of a lamp device, and the length-unrestricted bar-like lamp device is continuously manufactured, thus fixing the conductive unit and the light source units conjoined to the conductive unit in good condition. This manufacturing method is convenient in working and manufacturing and flexible in production, and can reduce manufacturing cost drastically.
