We adopted the spectrum analysis method and the BAYTAP_G method to analyze the geoelectric potential data at the Niijima station during 1998～2000 After the quantitative analysis of the tide response of geoelectric potential changes at the above station, we obtained some main characteristics of the tide response. Besides the tidal components with various periods such as diurnal tide, semidiurnal tide, and so on, semimonthly and semiyearly variations of tide response were also detected from the geoelectric potential data at the Niijima station.
