OPTICAL DEVICE AND OPTICAL TRANSMISSION APPARATUS USING THE SAME

The invention provides an optical device and an optical transmission apparatus using the optical device. The optical device can suppress electrical short circuit between a lead disposed on a side surface of a housing and a cover member and can be miniaturized. The optical device is provided with a housing for housing at least an optical waveguide element, and is characterized in that a main body (1) of the housing has an opening (OP) on one surface and a pin (PN1) fixed to a side surface adjacent to the one surface, and the optical device is provided with: a metal member (2) disposed so as to surround the opening; and a cover member (11) that closes the opening and is joined to the metal member, the metal member and an end portion of the cover member along a side surface of the main body portion on which the lead is disposed being positioned further to the inside of the main body portion than the side surface of the main body portion. 本发明提供一种光器件和使用该光器件的光发送装置，该光器件抑制配置于壳体侧面的引脚与盖构件的电短路并能够小型化。光器件具备至少收容光波导元件的壳体，其特
