A terahertz wave generation element is provided, which includes: an optical waveguide including a core of electro-optic crystal; an optical coupler for extracting a terahertz wave generated from the optical waveguide when light propagates in the optical waveguide to a space; the terahertz wave generated by the light propagating in the optical waveguide from the optical waveguide has a polarization direction of electric field that is P polarization with respect to the emergence surface of the optical coupler, and an incident angle of the terahertz wave to the emergence surface is set to satisfy the Brewster condition. |
