A window frame (1) for installation in the exterior shell (5) of an aircraft comprises at least one outer flange (2), an inner flange (3), and a vertical flange (4) arranged perpendicular to and between these flanges, whereby the connection with the aircraft structure takes place via the outer flange (2) and whereby on the inner flange (3), a window element to be held is attached, which is held via the vertical flange (4). The window frame (1) comprises resin reinforced with fiber web semifinished parts, whereby the progression of the layers of the webs in the three regions of the outer flange, inner flange, and vertical flange, respectively, follow the mechanical load direction. For manufacturing, a semifinished part (10) made from reinforced web (20, 21, 22) 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.
