The invention relates to an electric toothbrush ( 10 ) having a rechargeable energy store ( 24 ) that is arranged in an inner space ( 36 ) in the body ( 12 ) of the toothbrush ( 10 ). The inner space ( 36 ) is sealed by a primary sealing element ( 56 ) against splash water and other detrimental influences. At least one contact element ( 28 ) for an external power supply unit ( 46 ) produces an electrically conductive connection to the energy store ( 24 ). The contact element is located either within the inner space ( 36 ), it being possible for the primary sealing element ( 56 ) to be removed for charging purposes, or outside the inner space ( 36 ), in which case it is optionally protected by an additional secondary sealing element ( 76 ). The invention also relates to a process for producing such a toothbrush.
