    Abstract: Alloy particles for negative electrode active material are proposed, which can impart anti-oxidation property to Si-containing alloy particles, and suppress oxidation of the negative electrode active material due to electrolyte at a considerably high level. A negative electrode material of secondary battery is achieved by a negative electrode material of secondary battery which is capable of intercalating and de-intercalating lithium and which consists of alloy particles including a silicon phase, a metal phase and bismuth, in which a crystallite size of the silicon phase is 10 nm or smaller, and the metal phase includes at least one kind of metal alloying with silicon but not with lithium, and the negative electrode material includes primary particles formed at least by the silicon and the metals.
