An endoscope includes an outer shaft with a distal end whose surface is configured by a cylindrical mantle surface and a curved front surface, such that the distal end of the outer shaft includes a mantle component and a curved front component that is joined to the mantle component. A distance of an interface between the mantle component and the front component from an edge between the mantle surface and the curved front surface is no greater than a wall thickness of the mantle component or no greater than a wall thickness of the front component.
