<p>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.</p> |
