PROBLEM TO BE SOLVED: To provide a dynamic microphone for ensuring a frequency response up to a low frequency by allowing a diaphragm, even with a small diameter to easily move when the diaphragm receives a sound pressure and capable of ensuring the sensitivity, by permitting taking up of a full wide area for a center dome part. SOLUTION: The dynamic microphone includes the diaphragm 6 for receiving sound waves and vibrates, and a transducing section for electrically acting on the diaphragm 6 for transducing vibration into an electrical signal. External circumferential edge part of the diaphragm 6 is in line contact with a support, and the line contact part is fixed to the support by an adhesive 66. The adhesive 66 is an adhesive having elasticity, even after curing. The diaphragm 6 includes the center dome part 61 and a sub dome part 62 on its outer circumferential side, and the outer circumferential edge part of the sub dome part 62 is fixed to the support through adhesion.
