Pane having an electrical connection element

A pane, comprising:

• a substrate, the substrate having a first coefficient of thermal expansion from 8×10−6/° C. to 9×10−6/° C.,
• at least one electrical connection element,
• an electrically conductive structure on a region of the substrate,
• a layer of a solder material on a region of the electrically conductive structure,
• wherein each of the at least one electrical connection element
• has a second coefficient of thermal expansion from 10×10−6/° C. to 13×10−6/° C., wherein a difference between the first coefficient of thermal expansion of the substrate and the second coefficient of thermal expansion of the connection element is less than 5×10−6/° C.,
• contains at least 50 wt. % to 89.5 wt. % iron, 16 wt. % to 20 wt. % chromium, and one or more elements selected from the group of carbon, nickel, manganese, molybdenum, and titanium,
• has at least two soldering points on the solder material, which form two contact surfaces, separated from each other, between the at least one electrical connection element and the electrically conductive structure, wherein the two contact surfaces are connected to each other via a surface of a bridge facing the substrate, and
• wherein a shape of each of the two contact surfaces has at least one segment of an oval, an ellipse, or a circle with a central angle α of at least 90°.
