<p>PROBLEM TO BE SOLVED: To improve outward appearance by eliminating a shadow of a base part for connecting use, and facilitate formation of a fine cross section. SOLUTION: Bases 3 having lamp pins 2 respectively existing by two pieces are provided in the vicinity of both end parts of a bulb 1 formed in an almost straight tube shape. The bases 3 are formed so as to be protrusively arranged in the almost vertical direction from a peripheral side surface in the vicinity of both end parts of the bulb 1, and the lamp pins 2 arranged on the bases are almost juxtaposed on a straight line in parallel to the axial direction of the bulb 1, and are protrusively arranged in the almost vertical direction to a tubular peripheral side surface of the bulb 1.</p> |
