We reformulate Dubrovin’s almost duality of the Frobenius structure to the setting of the Saito structures without metric. Then, we formulate and study the existence and uniqueness problem of the natural Saito structure on the orbit spaces of finite complex reflection groups from the viewpoint of the almost duality. We give a complete answer to the problem for the irreducible groups.Communicated by: Alexander Veselov
