LIGHT BULB AND MANUFACTURING METHOD OF LIGHT BULB

PROBLEM TO BE SOLVED: To make disposal easy by eliminating necessity for classification for disposal of a light bulb and to simplify the manufacturing process method of the light bulb. SOLUTION: A bulb-part holding body 2 is provided with a shell part 10 of conductive resin, insulation resin part 12 filled in the shell part 10 with a glass bulb 3 buried, and an eyelet part 11 of conductive resin fitted at the bottom of the insulation resin part 12. One of electrode lines 5 of a light bulb part 1 is arranged between the shell part 10 and the insulation resin part 12, and the other electrode line 6 is buried in the insulation resin part 12 while its tip part is buried in the eyelet part 11. The manufacturing method consists of a first molding process for molding the insulation resin part 12 by inserting the light bulb part 1, and a second molding process for molding the shell part 10 and the eyelet part 11.
