This invention regards a hearing aid (2) for at least partial insertion into an ear canal. The hearing aid has a faceplate (1), a battery holder (3) and a battery and a signal path comprising a microphone (12), a signal processor, and a receiver, where the microphone (12) and the battery are arranged at the faceplate (1). Further there are provided one or more electrical contact elements for electrical communication with the signal processor, where the contact elements each has a first leg (8; 8.1) arranged to be contacted from the outside of the hearing aid and a second leg (9; 9.1) arranged to provide electrical contact with the signal processor, and an intermediate part (10; 10.1) embedded in the surrounding material and interconnecting the first and second legs. The first legs of the contact elements are arranged to extend along a first side of the microphone (12) in the space between the microphone (12) and the battery holder (3) and the second legs of the contact elements are arranged at a second side of the microphone (12). The invention further concerns a separate module (11) with the contact elements where the module also has means for holding the microphone (12).
