In this paper, we consider three types of sums of products of poly-Bernoulli functions and derive Fourier series expansions of them. In addition, we express those three types of functions in terms of Bernoulli functions.

Fourier series, Bernoulli polynomial, poly-Bernoulli polynomial, poly-Bernoulli function.
