A sensor element for detecting a level of a gas component in the measured gas or a temperature of the measured gas. The sensor element includes at least one solid electrolyte layer. The solid electrolyte layer has at least one plated-through hole. The sensor element further includes a conductive element, which produces an electrically conductive connection through the plated-through hole. In the plated-through hole, the solid electrolyte layer is electrically insulated from the conductive element by an insulating element. At least one opening region of the plated-through hole is stabilized against phase transition by a stabilizing element. The stabilizing element is 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, W. A method for manufacturing the sensor element is also provided.
