#### Abstract

As a continuation of the authors’ and Wakatsuki’s previous paper [5], we study relations among Dirichlet series whose coefficients are class numbers of binary cubic forms. We show that, for all integral models of the space of binary cubic forms, the associated Dirichlet series satisfy self-dual identities.
