A method for producing a handle apparatus includes providing an elongate handle base body which has a central receiving space in which electronic components are arranged, applying a sealing joint around the central receiving space and attaching a handle cover to the elongate handle base body. When the handle cover is attached, the sealing joint is compressed so that the central receiving space is sealed via the sealing joint. An inlet opening and an outlet opening are formed on opposite ends of the central receiving space. The handle apparatus is oriented vertically and filled with a liquid sealing compound via the inlet opening, wherein gases which are present in the central receiving space are discharged via the outlet opening. A corresponding handle apparatus is also disclosed.
