Provided are conductive fine particles that are capable of reducing costs, have excellent conductive properties, and can be made thin when, for example, a composition mixed with resin is formed into a sheet shape. The conductive fine particles according to the present invention are formed of a nuclear body comprising a conductive material, and a covering layer comprising another conductive material that covers the nuclear body, whereof at least a portion forms the outermost layer. A circle diameter coefficient obtained from the following formula (1) is between 0.15 and 0.4, and at least one of a cut that has an outer edge shape and a branching leaf is provided in a plural number. [Formula 1] circle diameter coefficient = (area×4pi)/(perimeter)2sssFormula (1)
