An actinic ray-sensitive or radiation-sensitive composition, and an actinic ray-sensitive or radiation-sensitive composition obtained by the method for producing an actinic ray-sensitive or radiation-sensitive composition each contain a cation having a metal atom, and a ligand, in which a value of σ represented by Equation (1) is 2.2 or less. A pattern forming method and the method for manufacturing an electronic device each use the actinic ray-sensitive or radiation-sensitive composition. σ = ∑ k = 1 N ⁢ { ( μ - X k ) 2 × y k } ( 1 )
