Abstract: Provided are metal particles for an adhesive paste, a solder paste composition including the same, and a method of preparing the metal particles for an adhesive paste. The metal particles for an adhesive paste may include a core including one or more metal materials; and a shell arranged on part or an entirety of the core and including one or more metal materials. The metal material of the core may have a melting point higher than that of the metal material of the shell. An intermetallic compound is capable of being formed between the metal material of the core and the metal material of the shell. A ratio (D90/D10) of the 90% cumulative mass particle size distribution (D90 size) to the 10% cumulative mass particle size distribution (D10 size) in a particle size distribution of the metal particles may be 1.22 or less.
