PROBLEM TO BE SOLVED: To provide a raw material for a carbonaceous material, a silicon-containing carbonaceous material, a negative electrode of a secondary battery, and a lithium secondary battery, capable of displaying high charge and discharge capacity. SOLUTION: This raw material for the carbonaceous material is composed of a carbonaceous material (A) containing silicon and a carbonaceous material (B) containing no silicon, and the carbonaceous material (A) contains composite conductive particles (R) formed by attaching carbon black particles (Q) on the surface of silicon-containing particles (P), and carbon precursors (S).
