Dielectric-constant measurements of a hydrogen-bonded crystal CsH2PO4 were carried out at low temperature (4 K < T < 300 K) under high pressure up to 3.0 GPa. By the dielectric measurements, we discovered two new high-pressure phases at about 1.3 GPa and 2.55 GPa, which are named as phases V and VI, respectively. These phases have a stable pressure region higher than that of the previously reported phase AFEII. On the other hand, at ambient temperature two phase transitions were previously found at 2.9 and 4.1 GPa through X-ray diraction study. However, we could not observe any anomaly corresponding to these phase transitions in the present dielectric measurement.
