Abstract
The waveguide element includes: a dielectric portion having holes periodically formed in a substrate made of a ceramics material; a low-dielectric constant portion having a dielectric constant smaller than a dielectric constant of the dielectric portion; and a support substrate arranged below the dielectric portion, the support substrate being configured to support the dielectric portion. The waveguide element is configured to guide an electromagnetic wave having a frequency of 30 GHz or more and 20 THz or less, and a frequency range of the electromagnetic wave in which an absolute value of a propagation loss becomes 1 dB/cm or less is 50 GHz or more.
