ことを特徴とする圧力センサー。 A pressure sensor in which a diaphragm is disposed inside a main body, and the pressure acting on the diaphragm is transmitted to a pressure detection element through oil filled in a space between the diaphragm and the main body to detect the pressure. A pressure sensor, characterized in that the surface facing the diaphragm matches the shape of the diaphragm, and the space filled with oil in close proximity is reduced.
