で挟圧したことを特徴とする酸素分圧計。[Claims for Utility Model Registration] A bottomed cylindrical solid electrolyte body having a reference electrode on the inner surface of the closed end and a measurement electrode on the outer surface thereof, as well as a gas inlet to be measured. In an oxygen partial pressure meter, the solid electrolyte is housed in a shaped outer tube, and the measuring electrode is disposed between the outer tube and the closed end of the outer tube. The closed end of the solid electrolyte body is composed of a plate-like body made of 50% by weight or more of Au-platinum group metal alloy and has a planar shape that does not protrude from the peripheral edge of the outer surface of the closed end of the solid electrolyte body. A thin film-like bonding layer made of a noble metal material is integrally provided on the outer surface of the end, and the measurement electrode is connected to the closed end of the solid electrolyte body and the closed end of the mantle via the bonding layer. An oxygen partial pressure meter characterized by a pressure between the two parts.
