▎ 摘　　要

NOVELTY - Composite material comprises carbon material (21) and the metal oxide layer (22) which coat or covers the surface of the carbon material. The thickness of the coverage of the metal oxide layer is 95 wt.% or more, and is 10 nanometer (nm) or less. USE - Composite material used in the negative electrode material for lithium ion secondary batteries (claimed). ADVANTAGE - The composite material provides a negative electrode layer by the low pressurization, and high capacity or capacitance and a high output characteristic can be acquired. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a negative electrode material for lithium ion secondary batteries, which comprises composite material; and (2) a method for manufacturing composite materia, which involves preparing precursor solution containing the solvent of the metal oxide, precursor chosen from a metal alkoxide and a metalcomplex to obtain the base layer formation carbon material which formed the base layer for a metal oxide layer in carbon material, spraying the precursor solution with respect to the base layer formation carbon material made into the fluid state, heat-processing the base layer formation carbon material to which the metal oxide precursor adhered,and forming a metal oxide layer. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of composite material. Carbon material (21) Metal oxide layer (22)
