SOLUTION: The nurse call cordless handset with the hearing aid function has a removable earphone for the hearing aid and is constituted to communicate with a nurse call main machine using a microphone for transmission and a speaker for receiving or the earphone for the hearing aid in a nurse call situation (including both situations of a nurse call calling situation initiated by a call button operation and a nurse call communication situation) and to exert the hearing aid function by the microphone and the earphone for the hearing aid in a nurse non-call situation.
