Abstract
A waveguide element includes a waveguide member capable of guiding an electromagnetic wave having a frequency of 30 GHz or more and 20 THz or less. The waveguide member includes: an inorganic material substrate; and a conductor layer arranged above the inorganic material substrate. A thickness “t” of the inorganic material substrate satisfies the following expression (1): where 't' represents the thickness of the inorganic material substrate, λ represents a wavelength of an electromagnetic wave to be guided by the waveguide member, ε represents a relative dielectric constant of the inorganic material substrate, and “a” represents a numerical value of 3 or more.
