Kink-antikink interaction is numerically studied in a system of a perturbed sine-Gordon equa-tion. We sttrdy a system in which a kink and an antikink are localized by placing two impuritiesbetween them. The kink and the antikink oscillate chaotically near the irmpurities by applyingthe external force. We observe kink-antikink motion with changing the strength of coupling,where the strength of coupling can be changed by changing the distance between two impurities.Tinae series of the distance between two kinks shows similar characteristics to that in the cottpledchaotic oscillator system. An intermittency caused by chaos-chaos interaction is also observed.Power spectrum of this intermittency is a type of 1 / f.
