Abstract

　入出力電極の実装基板の信号線への接続形態を複数確保し、カバーを用いずに上面側の外導体をアース電位に落とした誘電体フィルタの提供を図る。誘電体ブロック（２）は略直方体形状であり、下面で実装基板に実装される。内導体（５Ａ～５Ｃ）は、誘電体ブロック（２）の正面を開放端として内導体形成孔の内面に形成されている。入出力電極（４Ａ，４Ｂ）は誘電体ブロック（２）の下面に設けられていて、誘電体ブロック（２）の側面と下面との境界から、誘電体ブロック（２）の正面と下面との境界にかけて延設されている。外導体（３）は、下面電極隅部（３１Ａ．３１Ｂ）と下面電極主部（３２）とを含み、実装面で接地される。下面電極隅部（３１Ａ．３１Ｂ）は、誘電体ブロック（２）の下面の、誘電体ブロック（２）の正面と側面とのなす隅に設けられている。
