In a pressure and pressure difference transmitter (40, 200) that seals a sealing liquid (80) for transmitting the pressure inside a pressure leading passage (60), the pressure and pressure difference transmitter (40, 200) forming a space between a diaphragm (50) and a main body side wall surface, including the pressure leading passage (60) connected to the main body side wall surface, and transmitting the pressure received by the diaphragm (50) to a sensor (130) through the sealing liquid (80) sealed in the space and the pressure leading passage (60), a hydrogen occluding material (90) for occluding hydrogen atoms (310, 361) of the sealing liquid (80) is disposed at least in the sealing liquid (80), the main body side wall surface, or a part of a portion from the main body side wall surface to the sensor (130), with the hydrogen occluding material (90) being formed with an uneven shape on the surface or being attached with a granular hydrogen occluding material (410, 440). |
