There is provided a dynamic microphone in which vibration noise generated by the rolling of a microphone unit caused by a vibration component perpendicular to the principal axis direction of the microphone is reduced effectively. In the dynamic microphone including a microphone unit 110, an inner cylinder 120 having a back air chamber. in the structure thereof constituting a microphone body 10 together with the microphone unit 110, and a microphone casing 20 serving as an outer cylinder, in which a part of the inner cylinder 120 of the microphone body 10 is supported by a floating type vibration-proof structure using an elastic member 30, a weight 40 for causing the center of gravity O of the microphone body 10 to coincide with a supporting point S using the elastic member 30 is attached to the inner cylinder 120 so as to be preferably movable.
