Abstract: A terahertz wave temporal waveform acquisition apparatus includes a light source, a branch part, a terahertz wave generation element, a terahertz wave detection element, a delay providing medium, a temperature adjustment unit, and an analysis unit. The delay providing medium is disposed on an optical path of a terahertz wave from the terahertz wave generation element to the terahertz wave detection element, is formed of a material of which a refractive index for the terahertz wave depends on the temperature, and provides a delay according to the temperature to the terahertz wave.
