A window frame (1) for installation in the exterior shell of an aircraft comprises in each case at least one outer flange (2), one inner flange (3), and one vertical flange (4) arranged perpendicular to and between these flanges (2, 3), wherein the connection with the aircraft structure (5) is realized via the outer flange (2) and wherein on the inner flange (3), a window element (7, 8) to be held is attached, which is held via the vertical flange (4). The window frame (1) comprises resin reinforced with unidirectionally arranged fiber bundles (20), wherein the progression of the fiber bundles in the three regions of the outer flange (2), inner flange (3), and vertical flange (4), respectively, follow the mechanical load direction. For manufacturing, a semifinished part made from unidirectionally arranged fiber bundles is inserted into a molding tool (11), in which, under pressure and temperature, resin is injected, and the component made in this manner is hardened subsequently in the molding tool(11).
