The modulated phases and the successive phase transition of thiourea are reinvestigated by means of dielectric measurements and X-ray scatterings. In the E-T phase diagram, eightfold and ninefold superstructures are designated in h-thiourea. There remain some discommensurations as domain walls in the ferroelectric phase. The structure of discommensurations is discussed based on the structural analysis of the superstructures at -95℃ and -103℃.
