    • A green sheet (11) including a first dielectric is provided with of holes h a specified pattern penetrating the green sheet in the thickness direction. The green sheet (11) provided with of holes h the specified pattern are then laminated to obtain a dielectric block (13) arranged with air gaps a specified pattern periodically. A second dielectric is arranged in the air gap of the dielectric block (13). A photonic crystal periodically arranged with the first dielectrics and the second dielectrics having a dielectric constant different from that of the first dielectric can thereby be obtained without requiring particularly complicated processes. When dielectric ceramics is employed as the first and second dielectrics, a small photonic crystal having high characteristics can be obtained. Alternatively, dielectric ceramics and air may be employed, respectively, as the first and second dielectrics.

    • Columnar structures (101) define tetragonal lattices (104), and a photonic crystal (100) has a periodic construction in which the tetragonal lattices (104) are periodically arranged. Let the distance between the centers of the columnar structures (101) be a unit length (a), and let the same be the lattice constant of the tetragonal lattices (104). And a columnar structure (102) is arranged substantially at the center of each tetragonal lattice (104), and dielectric regions (103) are disposed around the peripheries of the columnar structures (101, 102). Employment of this arrangement ensures that in a certain common frequency range, a photonic gap with respect to TE waves and a photonic gap with respect to TM waves are formed, making it possible to form a complete band gap.
