The paper deals with the study of the Bardeen-Cooper-Schrieffer integral equation which appears in the theory of superconductivity. Assuming the positiveness of the kernel of that equation it is shown that there exists a unique finite transition temperature \(T_ c\) such that if \(T<T_ c\) then the equation in question possesses a positive solution. Moreover, it is proved that such a solution may be approximated by a sequence of solutions of the Bardeen-Cooper-Schrieffer equation restricted to bounded domains.
