PROBLEM TO BE SOLVED: To easily and reliably connect a lighting circuit to an eyelet and prevent non-lighting caused by a defective contact by forming a base section having the eyelet and a screw-like shell at one end section of a case storing the lighting circuit in it, and connecting the light circuit to the eyelet without using a lead wire. SOLUTION: A printed board 5a is arranged in parallel with the center axis of a case 2 in the case 2, thereby an eyelet 8 can be directly mounted on the printed board 5a easily. The interval between the printed board 5a and eyelet 8 can be reduced, and the eyelet 8 can be directly mounted easily on the printed board 5a. Since the printed board 5a can be arranged in the cylinder section 2a of the case 2, the space in the case 2 can be utilized effectively, and this tubular bulb can be made compact. |
