Abstract
A terahertz wave generating device includes a plurality of light sources and an antenna. The light sources are configured to generate pulsed light. The antenna is configured to generate terahertz waves by being irradiated with the pulsed light generated by the light sources. The antenna has a plurality of pairs of electrodes with the electrodes in each of the pairs facing each other across a gap portion with a predetermined distance. The light sources is configured to irradiate the gap portions between the electrodes in the pairs with the pulsed light such that the gap portions between the electrodes of at least two of the pairs are irradiated with the pulsed light at mutually different timings.
