The present invention, the initial irreversible capacity due to decomposition of the non-aqueous liquid electrolyte, the purpose of low gas generation, to provide a useful non-aqueous secondary battery negative electrode for the active material for the production of an excellent non-aqueous secondary battery stability of the charge-discharge cycle do. The present invention, insertion and desorption is possible active material of a lithium ion (A) and an organic compound active material for a nonaqueous secondary battery negative electrode containing (B), and the organic compound (B) are sparingly soluble in non-aqueous liquid electrolyte, π conjugate has a structure, also it relates to the electrical conductivity of the active material for the 0.1 S / ㎝ or less non-aqueous secondary battery negative electrode according to 25 ℃.
