Abstract: An active material having a high capacity for negative electrodes of nonaqueous secondary batteries is provided by pyrolysis of a composite resin (A) which has a silanol group and/or a hydrolysable silyl group and which contains a polysiloxane segment (a1) and a polymer segment (a2) other than the polysiloxane segment (a1), and furthermore, a negative electrode using the above active material and a nonaqueous secondary battery including the above negative electrode are also provided. In addition, by pyrolysis of a dispersion liquid obtained from the composite resin (A), silicon particles, and an organic solvent, an active material having a high capacity for negative electrodes of nonaqueous secondary batteries is provided, and furthermore, a negative electrode using the above active material and a nonaqueous secondary battery including the above negative electrode are also provided.
