とを特徴とする一端封止型電球。[Scope of Claim for Utility Model Registration] A glass sealed tube having the remainder of an exhaust pipe for exhausting and introducing sealed gas at one end and an airtight sealing portion at the other end; a filament coil arranged to extend along the filament coil, one inner conductor wire and the other inner conductor wire connected to one end and the other end of the filament coil, respectively, and the hermetically sealed wire connected to these inner conductors, respectively. The exhaust pipe of the filament coil includes a sealing conductor hermetically buried in the sealing conductor, and an outer conductor connected to each of these sealing conductors and protruding outward from the hermetically sealed portion. In the one-end sealed light bulb, the tip of the connecting portion between one end of the remaining part of the inner conductor and the inner conductor is located within the remaining part of the exhaust pipe, wherein the remaining part of the exhaust pipe in the glass sealed tube is provided. 1. A one-end sealed light bulb, characterized in that the inner wall of one end of the exhaust pipe is formed into a slope shape with an opening angle of 120 degrees or less that widens as it moves away from the part where the rest of the exhaust pipe is located.
