An infrared effective theory of quark confinement is proposed with the aid of a dual vector potential and a complex scalar monopole field. A static potential between charged sources is composed mainly of the linear and the Yukawa interaction. The existence of a light neutral axial-vector boson and a massive scalar boson not composed of quarks is suggested.
