    摘要： The present invention relates to a process for producing a composite cathode active material for a nonaqueous electrolyte secondary cell which is subjected to surface treatment, comprising:
    previously mixing the cathode active material with a surface-treating component in the form of a metal compound containing one or more metal elements selected from the group consisting of the first transition series elements and the second transition series elements; and
    then coating the cathode active material with the surface-treating component using an apparatus capable of effecting a high-speed shearing action.
