PROBLEM TO BE SOLVED: To provide a particle producible without using a compound having active hydrogen and useful as a component of an addition polymerization catalyst, a method for producing the particle, the use of the particle, the addition polymerization catalyst producible without using a compound having active hydrogen and a method for producing an addition polymer by using the addition polymerization catalyst. SOLUTION: The modified particle is produced by contacting (a) M<SP>1</SP>L<SP>1</SP><SB>m</SB>(M<SP>1</SP>is a typical metal atom of the group 1, 2, 12, 14 or 15; m is the valence of M<SP>1</SP>; and L<SP>1</SP>is a hydrogen atom, a halogen atom or a hydrocarbon group), (b) a compound expressed by general formula [2] (R<SP>1</SP>and R<SP>2</SP>are each a hydrocarbon group or a substituted hydrocarbon group; R<SP>3</SP>is a hydrocarbon group or a halogenated hydrocarbon group; and E is a non-metallic atom of the group 16), (c) R<SP>3</SP><SB>t-2</SB>TH<SB>2</SB>(T is a non-metallic atom of the group 15 or 16; and t is the valence of T) and (d) a particle.
