Sensor element for detecting at least one property of a measured gas in a measured gas chamber, and method for manufacturing the same

A sensor element for detecting a level of a gas component in a measured gas or a temperature of the measured gas, the sensor element comprising:

• at least one solid electrolyte layer, the solid electrolyte layer having at least one plated-through hole;
• and
• a conductive element which produces an electrically conductive connection through the plated-through hole, from an upper side of the solid electrolyte layer to a lower side of the solid electrolyte layer, wherein in the plated-through hole, the solid electrolyte layer is electrically insulated from the conductive element by an insulating element;
• wherein at least one opening region of the plated-through hole is stabilized against phase transition by a stabilizing element, the stabilizing element being made at least partially of a material, which includes a noble metal and an element selected from the group consisting of V, Nb, Ta, Sb, Bi, Cr, Mo, and W, and
• wherein the stabilizing element surrounds the opening region one of:
• (i) completely in a circumferential direction, or (ii) annularly.
