Abstract

An aircraft window includes: a window body including window panels, and an electromagnetic shield layer laminated on the window panels; a window frame that is made of a conductive material, and that surrounds the window body; a rubber-based gasket provided with conductivity, the gasket being at least partially held between the window body and the window frame; and a conductive layer that is located between the window body and the gasket, and that brings the electromagnetic shield layer and the gasket into conduction with each other. The window frame includes a holding section that holds the window body. At least a part of the conductive layer extends to a portion of the window body facing an extending part of the holding section. Moreover, the conductive layer extends about an entire perimeter of the window body, and extends only partially along an interface between the window body and interposition member.
