A modular hearing aid having separate micro- phone, receiver, amplifier and battery modules. The microphone module is connected to the receiver module by two dovetails. The receiver module is connected to the amplifier module by one dovetail and to a forwardly pro- jecting plate of the battery module by another dovetail. The amplifier module is connected to the battery module by another dovetail. A flexible circuit board of the amplifier module has a flap which extends over part of the receiver module and is soldered to pins projecting therefrom. The pins extend within the receiver housing and are connected to the receiver therein. Another flap of the circuit board extends over part of the battery module and is soldered to connections on the battery module. Another flexible circuit board extends from the amplifier module over the receiver module and is con- nected to pins on the microphone module housing. Cover plates cover the top and bottom of the assembled modules to provide a cosmetically attractive appearance.
