置。One pressure chamber of a diaphragm chamber defined by a diaphragm and a pressure introduction chamber of a pressure sensor are connected and connected in a sealed state via a connecting means, and two fluids are introduced into the other pressure chamber of the diaphragm chamber. In a pressure detection device in which pressure is detected by a pressure sensor through a diaphragm, a wall forming a closed space formed by connecting one of the pressure chambers and a pressure introduction chamber of the pressure sensor communicates with outside air. A pressure detection device characterized in that a hole is provided and the communicating hole is closed after being connected by the connecting means.
