Abstract

　この発明は、素子特性の劣化防止と小型化を両立させるための構造を備えた光導電アンテナ素子に関する。当該光導電アンテナ素子(17)は、半導体層(19)上に形成された一対の電極(21)を備える。各電極(21)は、アンテナ部(22)と、パッド部(23)と、これらを接続するライン部(24)から構成され、該ライン部(24)は、アンテナ部(22)から延在する平行部分(24a)を含む。また、一方の電極(21)のライン部(24)は、アンテナ領域(A)以外の部分が他方の電極(21)に対して反対方向に屈曲されており、該他方の電極(21)のライン部(24)も、アンテナ領域(A)以外の部分が一方の電極(21)に対して反対方向に屈曲されている。この構成により、当該光導電アンテナ素子(17)における素子特性の劣化防止と小型化が可能になる。
