Abstract
An alloy particle (5) includes: a core portion (1) made of an alloy that contains iron and silicon; and a coating portion (3) coating the core portion (1). The coating portion (3) contains Fe2SiO4, and, when measurement is performed on the coating portion (3) through X-ray diffraction, a strongest peak intensity of FeO is defined as IA, and a strongest peak intensity of the Fe2SiO4 is defined as IB, a peak intensity ratio (IA/IB) has a value of 0.2 or lower.
