Abstract
A heating element for a cooking appliance includes terminals that act as electrically conductive contact points. One or more buses are arranged between the terminals, and connect one or more heating element segments in a zig-zag configuration. The heating element segments are connected in series and are arranged parallel with one another. Each heating element segment includes a plurality of cutouts linked together and having an elliptical shape. The terminals, heating element segments, and buses are a continuous single sheet of conductive material. A method of making the heating element includes forming a pattern into the sheet of conductive material by etching the pattern into the conductive sheet using photolithography.
