ABSTRACT:
A hearing aid is used to be inserted into and removed from an ear hole. A cam attached to a taking-out knob pushes up a battery holder by lifting up the taking-out knob when the hearing aid is taken out from an ear hole, whereby the electrode of the battery in the battery holder is left from the battery connecting tongues attached to a panel portion to thereby turn OFF a power supply. A howling prevention fixture is fixed to a hearing aid case at the head portion thereof to prevent howling.
