Zusammenfassung:	To provide an optical waveguide element that enables connection by wire bonding and the like, reduces an amount of gold use, and prevents deterioration in conductor loss.SOLUTION: An optical waveguide element includes: a substrate 1 having an electro-optic effect; an optical guide 2 formed on the substrate; and control electrodes (30 and 31) provided on the substrate for controlling a light wave propagating through the optical guide. The control electrodes are formed of material other than gold, but gold is disposed at least at a wire bonded portion 4 of the control electrodes.SELECTED DRAWING: Figure 2 【課題】ワイヤボンディング等の接続が可能であり、金の使用量を抑制し、導体損失の劣化を抑制した光導波路素子を提供すること。【解決手段】電気光学効果を有する基板１と、該基板に形成された光導波路２と、該基板に設けられ、該光導波路を伝播する光波を制御する制御電極（３０，３１）とを備えた光導波路素子において、該制御電極は、金以外の素材で構成され、該制御電極の少なくともワイヤボンディングする部分４には、金が配置されていることを特徴とする。【選択図】図２
