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 ).
