A hearing aid includes a housing and a hook, the housing defining a top area and a bottom area, a front end and a rear end, and contains a microphone, an amplifier, a receiver, and a battery for power supply, and the hook is attached to the housing and transmits acoustic signals from the receiver into the ear of the user. The housing is provided by two connectable and detachable parts having lines of separation extending at least partly between top and bottom at both sides of the housing between the front end and the rear end, and means are provided in the front part for holding an amplifier circuitry board at one edge.
