とする絶対圧力変換器用気密端子。 A pressure-receiving diaphragm is integrally connected with the pressure-receiving surface facing the inner end of the introduction path of the pressure-introducing member that introduces the fluid to be measured, and the back side of the pressure-receiving diaphragm is surrounded by a cylindrical member to form a vacuum chamber. In the airtight terminal for an absolute pressure transducer, which is integrally provided in the cylindrical member of the absolute pressure transducer and which outputs a detection signal of a strain detection resistor attached to the back surface of the diaphragm to the outside of the vacuum chamber, A lead pin having at least one end processed into a flat shape is inserted into a small diameter through hole drilled around the working opening of the cylindrical member, which has a working opening formed in a portion facing the back surface of the diaphragm. The lead wire is inserted so that one end side faces the vacuum chamber and is airtightly fixed by a sealing member, and the other end of the lead wire, which has one end connected to the strain detection resistor in advance, is connected to the flat surface of the lead pin. An airtight terminal for an absolute pressure transducer, characterized in that the work of connecting the parts can be performed through the work opening.
