PURPOSE:To stabilize molding in a positive electrode section and improve electric properties and resistance to leak by forming a cross-sectional shape with a horizontal tip which makes contact to the positive electrode flux of a positive electrode ring into a knife-edged upper surface tip or a step which is raised from the lower surface side to the upper surface side. CONSTITUTION:The cross-sectional shape of a tip which makes contact to the positive electrode flux at the positive electrode ring horizontal section with an inverted L-shaped crosssection is formed into a knife-edged upper surface tip section with a sharp end or a step which is raised from the lower surface side to the upper surface side. Thus, the flux during molding flows smoothly in any directions A, B, and C and is supplied to even the horizontal tip section E' of the positive electrode ring. As a result, flux molding density can be made uniform and electric properties and resistance to leak be improved. |
