Abstract (en)

To provide a nickel fine particle which can easily form a conductive path when contained in a conductive paste. A nickel fine particle which is formed of a ring body having a ring shape is formed by oxidizing a nickel chloride fine particle and, thereafter, by reducing a nickel oxide fine particle. By forming the nickel fine particle into the ring body, affinity between the nickel fine particle and a binder resin is improved so that a conductive path can be easily formed.
