PROBLEM TO BE SOLVED: To provide a handset for mobile communication with which the user can make calls without taking out mobile communication every time from a bag, etc., and can clearly identify speaking voices from external sounds by catching the voice from inside of user's ears. SOLUTION: This handset for mobile communication is constituted in such a way that, when mobile communication receives a radio wave, a first transmitter-receiver 4 transmits a weaker radio wave than the radio wave to a second transmitter-receiver 5. The transmitter-receiver 5 has a speech transmitting-receiving section 7 which is formed by collectively bundling a microphone 10 for speech, a loudspeaker 11 for incoming an calling, and a loudspeaker 12 for speech in such a size that can be inserted into or put on the ear of the user, informs the user of the arrival of an incoming call at mobile communication upon receiving the weak radio wave from the first transmitter- receiver 4 through the transmitting-receiving section 7, and can make speech by mobile communication by transmitting a weak radio wave to the first transmitter-receiver 4 after receiving the weak radio wave.
