PURPOSE: Provided is a safety helmet enabling bone conduction communication to attach a bone conduction speaker and a bone conduction microphone on the inside of the helmet; to prevent an accident by wearing the safety helmet and to enable a user to communicate in a noisy environment without using an ear phone. CONSTITUTION: The safety helmet provided with a cushion member(12), a shock-absorbing belt(13), and a head band in a hemisphere-shaped inner circumferential surface(11) comprises a microphone/speaker assembly including a bond conduction microphone(21), a bond conduction speaker(22) and a cable(23) for connecting the bond conduction microphone and speaker. The microphone/speaker assembly includes a connection jack(23a) on the end of the cable(23) for connecting a wireless communication terminal and a flexible extension cable.
