。 A diaphragm is provided opposite to a protrusion provided in a flow path within the valve body, and the diaphragm is brought into contact with and separated from the protrusion by a valve shaft to change the cross-sectional area of the passage between the diaphragm and the protrusion. In the diaphragm valve, a piece made of the same material as the lining material of the diaphragm is disposed in the flow path on the downstream side of the protrusion, and this piece is provided with fluid in a manner corresponding to the downstream outer peripheral edge of the diaphragm. A diaphragm valve characterized by having a flow hole.
