PROBLEM TO BE SOLVED: To provide a conducting agent for nonaqueous secondary battery use superior in conductivity and dispersibility, and an electrode arranged by use thereof, and a nonaqueous secondary battery having such an electrode.SOLUTION: A boron-solid solution carbon black for nonaqueous secondary battery's conducting agent comprises: 0.05 mass% or less of water-soluble boron; 5 ppm or less of cohering particles having a size of 20 μm or larger and an electric resistivity of 0.15 &OHgr;cm or smaller, measured according to JIS K 1469; 50 ppm or less of sulfur components; and 0.1% or less of volatile components. A conducting agent for nonaqueous secondary battery use comprises the boron-solid solution carbon black for nonaqueous secondary battery's conducting agent. In the conducting agent for nonaqueous secondary battery use, the degree of dispersion of the boron-solid solution carbon black for nonaqueous secondary battery's conducting agent is 10 μm or smaller according to a grind gauge. |
