Fig. 1 is a schematic perspective view of a light bulb according to the present invention, Fig. 2 is a sectional view of a caulking type used for caulking the tip of the lead wire of the light bulb, and Fig. 3 shows that the leg of the filament of the light bulb is connected to the lead wire. FIG. 4 is a partially omitted perspective view showing a state in which the lead wire is gripped and swaged by the folded end of the lead wire, and FIG. FIG. 5 is a partially omitted perspective view of the lead wire showing the crimped tip in an open state; FIG. 6 is a partially omitted perspective view showing a state in which the leg portion of the filament of a conventional light bulb is held and swaged by the folded tip of the lead wire, and FIG. 7 is a partially omitted perspective view showing the tip of the lead wire. FIG. 3 is a partially omitted perspective view of the lead wire showing a state in which the caulked tip portion is open in order to explain the state of the abutment surface against the filament leg portion after caulking. 12...
