Abstract-
A terahertz electromagnetic wave generator according to the present disclosure includes: a substrate; a thermoelectric material layer which is supported by the substrate and which has a surface; and a pulsed laser light source system which locally heats the thermoelectric material layer with an edge of the surface of the thermoelectric material layer irradiated with pulsed light, thereby generating a terahertz electromagnetic wave from the thermoelectric material layer.
