    摘要： A negative electrode material according to the present invention which is provided as an inexpensive negative electrode material for a nonaqueous electrolyte secondary battery and which suppresses the amount of expensive Co which is used contains three types of powder materials in the form of alloy material A, alloy material B, and a conductive material. Alloy material A comprises an alloy having a CoSn 2 structure containing Co, Sn, and Fe and having an Sn content of at least 70.1 mass% and less than 82.0 mass%. Alloy material B comprises Co 3 Sn 2 and has a lower discharge capacity than alloy material A, and the proportion R B of the mass of alloy material B based on the total mass of alloy material A and alloy material B is greater than 5.9% and less than 27.1 %. The content of the conductive material is at least 7 mass% and at most 20 mass% based on the total mass of alloy material A, alloy material B, and the conductive material. The exotherm starting temperature determined by differential scanning calorimetry for this negative electrode material is less than 375.4° C.
