Abstract

　フェライト内部での磁場分布の乱れを減少させ、挿入損失特性及びアイソレーション特性を改善することのできる非可逆回路素子を得る。 　永久磁石により直流磁界が印加されるフェライト（３２）と、該フェライト（３２）に配置された第１及び第２中心電極を備えた非可逆回路素子。フェライト（３２）の上下面（３２ｃ），（３２ｄ）に形成した凹部（３７），（３８）に導電材が充填され、該導電材には第１及び第２中心電極が所定の回路を構成するように電気的に接続される。凹部（３７），（３８）の第１及び第２主面（３２ａ），（３２ｂ）に臨む開口部は、永久磁石による直流磁界の印加方向（Ａ）の上流側の開口部よりも下流側の開口部が大きく形成されている。
