A carbon material capable of obtaining a non-aqueous secondary battery having a high capacity and excellent input/output characteristics is provided, and as a result, a high-performance non-aqueous secondary battery is provided. A carbon material for a non-aqueous secondary battery containing graphite capable of occluding and releasing lithium ions, wherein the carbon material has an integrated pore volume of 0.08 ml/g or more in a pore diameter of 0.01 µm or more and 1 µm or less, flow type A carbon material for a non-aqueous secondary battery, characterized in that the circularity obtained from particle image analysis is 0.88 or more, and the ratio (PD/d50 (%)) of the pore diameter to the particle diameter represented by the following formula (1A) is 1.8 or less. PD/d50 (%) = Mode pore diameter (PD)/volume-based average particle diameter (d50) × 100 (1A) in the range of 0.01 µm or more and 1 µm or less of the pore diameter in the pore distribution obtained by the mercury intrusion method |
