    We calculate dc Josephson current through charge density wave (CDW) region connected to two superconductors (S1, S2) by tunnel junctions at zero temperature. We discover infrared anomaly of the dc Josephson current caused by phase mode in the long junction limit. In this limit, the Josephson current is proportional to the characteristic energy consisting of physical quantities in CDW region, while in the short junction limit, the Josephson current is similar to the Ambegaokar-Baratoff formula which is proportional to the energy gap of superconductor.
