Abstract: A pressure transmitter including tube-like pressure introducing pipes, a sealed-in liquid, the inside of the pressure introducing pipes being filled with the sealed-in liquid, pressure receiving diaphragms for receiving the pressures of measurement fluids, the pressure receiving diaphragms being set up in a state where one-side apertures in the pressure introducing pipes are blocked by the pressure receiving diaphragms, and a pressure sensor that is set up in common to the other-side apertures in the pressure introducing pipes in a state where the pressure sensor is exposed to the sealed-in liquid, wherein the sealed-in liquid is silicon oil containing phenyl groups, the pressure transmitter further including a hydrogen-storage material that is set up inside the pressure introducing pipes.
