PURPOSE: A composite for forming an elastic conductive pattern, a manufacturing method of the elastic conductive pattern, and an electric component are provided to improve elasticity of a pattern and to maintain high conductivity. CONSTITUTION: A base material is prepared(S110). A trench line of a regular interval having a wave pattern is formed on the base material(S120). A polymer-metal precursor compound pattern is formed by filling the inner side of the trench line with a polymer-metal precursor compound(S130). The polymer-metal precursor compound of the polymer-metal precursor compound pattern is changed into a gel-metal nanoparticle and a polymer gel-metal nanoparticle composite pattern is formed(S140). The polymer gel-metal nanoparticle composite pattern inside the base material is transferred on an acceptor material(S150).
