Role of charge density waves (CDW) on the superconducLing (SC) transition fern-perature, T., 111 a one-dimensional model is investigated by examining the relation between the insulating gap induced by the CDW and the band filling. In contrast to thefact that the gap destroys the SC state, it is shown that the CDW formation results inthe T. enhancement due to tlte increase of the density of states when the gap edge ex-ists near the Fermi point. Further the degree of the T. enhancement is examined in thepresence of the CDW fluctuation.
