The bone conduction microphone includes a vibration collection unit configured to come into contact with a human body and collect vibration in a predetermined direction, which is included in the vocal cord vibration, and a switch configured to switch whether collection of the vibration in the predetermined direction is enabled. The switch is disposed on a side of the vibration collection unit, which is opposite to a side configured to come into contact with the human body, to allow a direction of an operation of switching whether collection of the vibration in the predetermined direction is enabled to be parallel to the predetermined direction.
