Claims

[Scope of utility model registration request]

a main body, a chamber provided inside the main body and filled with a sealing liquid, a through hole opening from the chamber to both sides of the main body, a pressure receiving element attached to the main body, and a cantilever-shaped chamber in the chamber. In the capacitive differential pressure transmitter, the capacitive differential pressure transmitter includes a movable electrode supported by the main body and connected to the pressure receiving element via a rod, and a fixed electrode disposed opposite to the movable electrode at a constant interval. A slit is provided along the side of the electrode, and this slit forms a location with low rigidity, and the center portion of the movable electrode surrounded by the slit is connected to the rod while the tip of the electrode supporting portion remains stationary. A differential pressure transmitter characterized in that the surface and the constant electrode are fixed to the supporting part of the movable electrode and the immovable part of the tip part via a frame material. =
