PROBLEM TO BE SOLVED: To provide a core shell type noble metal nanocolloid particle in which the outer surface of a first noble metal composing a core is coated with a second metal, and having a particle diameter of≤10 nm. SOLUTION: The circumference of a noble metal core particle of≤8 nm is coated with a 1 to 6 atomic layer, i.e., with a second noble metal of≤1 nm, so as to provide a core shell type noble metal nanocolloid particle having a particle diameter of≤10 nm.
