PROBLEM TO BE SOLVED: To provide a more accurate quantification method for a shell coverage of core-shell particles, and a manufacturing method for core-shell particles to which the quantification method is applied.SOLUTION: An open-circuit potential of core-shell particles is measured, and for a mixed sample obtained by mixing particles of core metal material and particles of shell metal material, the sample having the same open-circuit potential as the measured value of the open-circuit potential of the core-shell particles, the ratio of the surface area of the particles of shell metal material to the sum of the surface area of the particles of core metal material and the surface area of the particles of shell metal material, is determined as a coverage of the core-shell particles. |
