Abstract: A film thickness measuring device including: a terahertz wave generator; a prism that has an entrance surface, an abutment surface capable of abutting a surface of a sample including a first film on a side where the first film is formed, and an emission surface; a terahertz wave detector that detects an S-polarization component and a P-polarization component of a reflected wave from the sample, emitted from the emission surface of the prism; and a control section configured to determine a thickness of the first film formed in the sample, based on a difference between a time waveform of the S-polarization component of the reflected wave and a time waveform of the P-polarization component of the reflected wave.
