PROBLEM TO BE SOLVED: To provide a method for producing a core shell type silver-tin composite particle not only having high blackness and excellent light shieldability, but also having excellent heat resistance and a reduced environmental load, to provide an inexpensive core shell type silver-tin composite particle, to provide a black material, to provide a black light shielding film, and to provide a black particle-dispersed liquid. SOLUTION: The core shell type silver-tin composite particle 1 has the average particle diameter of 1 to 300 nm, and has a structure where a tin particulate 2 essentially consisting of tin and also formed into the nucleus is covered with an outer shell layer 3 as a film with fine pores composed of at least one kind selected from silver, a silver-tin alloy, silver and a silver-tin alloy.
